Maximizing Your Investment: Tips for Planning and Budgeting Your Extension Cost

If you're considering extending your home or property, you already know it's a major investment. Maximizing that investment requires careful planning and budgeting. From adding an extra room to expanding your living space, a well-executed extension can increase your property value and create a more comfortable living environment.

In this article, we will provide you with tips and strategies for planning and budgeting your extension cost effectively. Whether you're working with a limited budget or have more flexibility, we've got you covered. Our aim is to help you make informed decisions, avoid unnecessary expenses, and ensure that your extension project is a success.

We will discuss key factors to consider when planning your extension, such as design ideas, local regulations, and finding reliable contractors. We will also explore budgeting techniques and offer advice on cost-saving measures without compromising on quality. Our goal is to empower you with the knowledge and insights needed to make the most of your investment and achieve the extension of your dreams.

The importance of planning and budgeting for extension costs

Planning and budgeting are essential steps in any extension project. Without a clear plan and budget in place, you may encounter unexpected costs, delays, and other challenges along the way. By taking the time to plan and budget properly, you can minimize risks and maximize your investment.

When planning your extension, it's important to consider your goals and objectives. Are you looking to create additional living space? Or do you need an extra room for a specific purpose, such as a home office or a playroom for your children? By clearly defining your goals, you can ensure that your extension meets your specific needs.

Another important factor to consider is the design of your extension. It's crucial to create a design that complements your existing property and blends seamlessly with its surroundings. This not only enhances the aesthetic appeal but also adds value to your property.

Factors to consider when budgeting for an extension

Before you start budgeting for your extension, it's important to consider various factors that can affect the overall cost. These factors include the size and complexity of the extension, the materials and finishes you choose, and any additional features or amenities you want to include.

It's also important to take into account any local regulations or permits that may be required for your extension. Depending on where you live, there may be specific building codes or zoning restrictions that need to be followed. Failing to comply with these regulations can result in costly fines or delays in your project.

Additionally, you should consider the potential impact on your property value. While an extension can increase the value of your home, it's important to ensure that the cost of the extension does not exceed the potential increase in value. It's a good idea to consult with a real estate professional or a property valuer to get an estimate of the potential return on investment.

Researching and estimating extension costs

Once you have a clear understanding of your goals and the factors that can influence your extension cost, it's time to research and estimate the costs involved. This can be done by gathering quotes from architects, suppliers, and other professionals involved in the project.

To get accurate estimates, it's important to provide detailed information about your extension plans. This includes the size and layout of the extension, the materials and finishes you want to use, and any additional features or amenities you require. The more specific you can be, the more accurate the estimates will be. This is where hiring a qualified architect can pay substantial dividends.

It's also a good idea to do some research on average extension costs in your area. This can give you a rough idea of what to expect and help you identify any potential cost-saving opportunities.

Creating a comprehensive extension budget

Once you have gathered all the necessary information and estimates, it's time to create a comprehensive extension budget. This budget should include all the costs associated with your extension, including materials, labor, permits, and any additional expenses.

Start by researching an estimated cost per square metre in your area. Be sure to include a contingency fund to account for any unexpected expenses that may arise during the project. It's a good idea to set aside at least 10% of your total budget for contingencies. Also do not forget VAT and keep in mind that this estimate should be treated as a very rough rule of thumb and not a reliable figure.

Next, prioritize your budget items based on your goals and preferences. If you're working with a limited budget, you may need to make some tough decisions and cut back on certain items. However, it's important to strike a balance between cost-saving measures and quality to ensure a successful outcome.

Tips for maximizing your extension budget

While it's important to create a realistic budget, there are several tips and strategies that can help you maximize your extension budget without compromising on quality.

First, consider the timing of your extension. Construction costs can vary depending on the time of year and market conditions. By scheduling your extension during the off-peak season or when contractors are less busy, you may be able to negotiate better rates.

Second, explore different material options. While high-end materials may be appealing, they can also significantly increase your costs. Look for cost-effective alternatives that offer similar benefits and durability. Remember, it's not always necessary to choose the most expensive option to achieve the desired result.

Third, consider doing some of the work yourself. If you have the skills and experience, taking on certain tasks can help reduce labor costs. However, it's important to be realistic about your abilities and only take on tasks that you're confident you can complete successfully.

Exploring financing options for your extension project

If you're working with a limited budget, you may need to explore financing options to fund your extension project. There are several options available, including personal loans, home equity loans, and home improvement loans.

Personal loans are unsecured loans that can be used for any purpose, including home renovations. They typically have higher interest rates and shorter repayment terms compared to other loan options.

Home equity loans allow you to borrow against the equity in your home. These loans offer lower interest rates and longer repayment terms, making them a popular choice for financing home improvement projects.

Home improvement loans are specifically designed for funding renovation projects. These loans often have lower interest rates and flexible repayment terms, making them an attractive option for extension financing.

It's important to carefully consider the terms and conditions of each financing option and choose the one that best suits your needs and financial situation. Be sure to compare interest rates, fees, and repayment terms to find the most favorable option.

Working with professionals: Hiring an architect and contractor

To ensure the success of your extension project, it's important to work with professionals who have the necessary expertise and experience. This includes hiring an architect to design your extension and a contractor to oversee the construction process.

An architect can help translate your ideas into a practical design that meets your needs and complies with local regulations. They can also provide valuable advice on materials, finishes, and other design elements. A thorough design will also allow to get precise quotes from several builders.

When hiring a contractor, it's important to do thorough research and obtain multiple quotes. Look for contractors who have experience in similar projects and have a good reputation in the industry. Ask for references and check online reviews to ensure that you're hiring a reliable and trustworthy professional.

Avoiding common budgeting mistakes during the extension process

During the extension process, it's important to avoid common budgeting mistakes that can undermine your project's success. One common mistake is not allowing for potential changes or modifications during the project. It's natural for things to evolve as the construction progresses, and you may need to make adjustments along the way. Be prepared for these changes and have a contingency fund in place to accommodate them.

Finally, it's important to track and monitor your extension budget throughout the project. Regularly review your expenses and compare them to your budget to ensure that you're staying on track. If you notice any significant deviations, take immediate action to address the issue and avoid any cost overruns.

How to track and manage your extension budget effectively

Tracking and managing your extension budget effectively is crucial to the success of your project. Here are some tips to help you stay on top of your finances:

1. Use a spreadsheet or budgeting software to keep track of your expenses. This will allow you to easily monitor your spending and identify any areas where you may be overspending.

2. Regularly review your budget and compare it to your actual expenses. This will help you identify any discrepancies and take corrective action if needed.

3. Communicate regularly with your contractor and other professionals involved in the project. Keep them informed of your budget constraints and ensure that they are aware of any changes or modifications that may affect the cost.

4. Be proactive in managing your budget. If you notice any potential issues or cost overruns, address them immediately to avoid any further complications.

By following these tips, you can effectively track and manage your extension budget, ensuring that your project stays on track and within your financial limits.

Conclusion: The benefits of proper planning and budgeting for your extension project

Proper planning and budgeting are essential for maximizing your investment and ensuring the success of your extension project. By taking the time to carefully plan your extension and create a comprehensive budget, you can minimize risks, avoid unnecessary expenses, and achieve the extension of your dreams.

Consider your goals and objectives, research and estimate extension costs, and create a realistic budget that prioritizes your needs. Maximize your extension budget by exploring cost-saving measures and financing options.

Work with professionals who have the necessary expertise and experience, and avoid common budgeting mistakes during the extension process. Track and manage your extension budget effectively to stay on top of your finances and ensure a successful outcome.

By following these tips and strategies, you can make the most of your investment, create a more comfortable living environment, and increase the value of your property.

Large home extension in hampton hill

We recently had the opportunity to visit one of our ongoing projects, which involves the expansion of a large, detached house located in Hampton Hill.

Initially, the property had a poorly constructed ground floor rear extension, along with a small dormer on the roof.

To enhance the existing layout of the house, our project included internal alterations as well as a new larger extension. This extension was specifically designed to create a harmonious open-plan kitchen, living, and dining area.

Furthermore, our plans incorporated the addition of a garden office, which could be utilized as a versatile space for activities such as a gym, study, or music room.

To maximize the available space, the existing garage of the property was transformed into an extension of the front room.

Moving on to the first floor, we designed a brand-new floorplan that resulted in the creation of 3 additional bedrooms, each equipped with its own en-suite bathroom.

At roof level, we devised a hip-to-gable conversion, complete with a rear dormer. This alteration gave rise to a splendid master bedroom, accompanied by a luxurious en-suite and walk-in wardrobe.

To ensure the property's overall thermal efficiency, we employed the use of external insulation. This approach not only enhances the energy efficiency of the house but also contributes to its sustainability.

Our visit to the construction site showcased the remarkable progress made on this project. The original structure of the property was preserved while incorporating various improvements and additions, all aimed at enhancing the functionality and aesthetic appeal of the house.

New local project in Hampton

One of our projects, which is just located around the corner from our office, has recently commenced on site. This project entails a loft extension as well as modifications to an existing ground floor rear extension.

Initially, the property featured an uninsulated loft extension, along with a ground floor rear extension that was constructed poorly. These extensions were found to be lacking in functionality and, as a result, the client sought the expertise of Square One Architects to enhance the overall layout of the property.

With regards to the ground floor, we made the decision to relocate the existing WC beneath the staircase. This strategic move enabled us to open the ground floor area, thereby creating a brand-new kitchen/diner space.

In addition, we introduced new rooflights and replaced the existing French doors with sleek, Crittal style doors.

Moving on to the loft level, we designed and implemented a new extension that corresponded with the existing outrigger, thereby enabling us to elevate the ceiling height of the first-floor bathroom. This newly created space is set to serve as an en-suite for the loft bedroom.

Recognizing the inadequacies of the previous loft en-suite, it was converted into a stylish dressing area.

To enhance overall comfort for the occupants and improve the thermal performance of the house, our project allowed for full insulation of the loft area.

Site visit in Kingston

Today we had the opportunity to visit one of our construction sites in Kingston, where we are working on an exciting project for a full extension to a large detached house. The progress is quite impressive, and we can't wait to see the project completed after Christmas. We will make sure to provide more images to keep you updated on the transformation!

This project started back in 2019 with the extension of a 4-bed detached house in Kingston. Initially, the property was extended at ground floor level to the back and side in 2012. This was preceded by a first-floor extension on the side in 1969. However, the client had plans for further expansion and received planning approval for a loft extension in 2015. Unfortunately, upon reviewing the room's size, they decided it wouldn't meet their needs, and construction was put on hold.

One of the main concerns expressed by the client was the lack of natural light, making it a top priority to improve the daylight intake in the house. In line with their requirements, our proposals focused on a number of key areas. Firstly, we planned to square off the rear extension at ground floor level, creating a new office that would benefit from a large skylight and window. Additionally, we designed a first-floor extension in this area, providing extra space for one of the bedrooms.

On the opposite side of the property, we designed a first-floor side extension with dual purposes: to provide valuable space for a home office at first-floor level and to increase the overall footprint of the house for a subsequent loft extension. The front of the house was also extended, resulting in a double-height space featuring generous glass surfaces that bring in natural light and create a visually striking entrance.

To accommodate the loft extension, we completely redesigned the roof. The new roof not only has a larger footprint but also stands higher than the existing one. This new volume, combined with a large rear dormer, allowed us to create a spacious master bedroom with breathtaking views of Richmond Park. This bedroom also boasts a generous en-suite bathroom and a walk-in wardrobe, providing the ultimate sanctuary for the homeowners.

We are proud of the progress that has been made on this project and are confident that the end result will be a stunningly transformed home, filled with natural light and offering an abundance of space. Stay tuned for more updates and visuals as we continue to bring this vision to life.

Project schedule #8 Loft extension in Isleworth

This project is for a loft extension on a house in Isleworth.

The property was a 3-bed semi-detached house on a quiet residential road of similar styled houses. The neighbouring properties had recently had works done including hip to gable conversions and rear dormers, giving the green light to the current property for similar opportunities to expand.

Working with the client we extended the loft through a hip to gable conversion transforming the space into a master bedroom with dressing area and an en-suite bathroom with a shower.

Following their request for ample natural light we designed a wide window that encompasses most of the bedroom to the rear with sweeping views of the garden and the trees beyond and installed multiple skylights so that both the bathroom and the staircase are filled with natural daylight. Using light colours and materials the new spaces reflect the natural illumination and make the space feel bright, airy, and spacious as is also shown in the photos.

The extension was made feasible without affecting the arrangements of the existing lower floor rooms. Through this small intervention the house benefitted through enlarged internal spaces, better lighting, and additional amenities. At the same time, it assisted in creating cohesion with the neighbouring houses retaining the local style.

House in Kingston under construction

We were thrilled to visit our project for a large extension and renovation of a detached house in Kingston and were delighted to see the progress being made. The construction works are moving at an impressive pace, and we anticipate the scaffolding being erected soon to commence the expansive loft extension. We will provide you with further updates in due course!

When we first arrived at the site during the early stages of the project, we were impressed by the scale of the plot on which the original detached house sat. In the 90s, an extension was added to the side of the house to create a utility area. However, upon closer inspection, it became evident that the built quality of this side extension left much to be desired, particularly in the case of its flat roof.

Taking into consideration the clients' feedback during our initial meetings, we carefully devised a design that prioritized their desire for a more spacious and open kitchen/dining/living area. To achieve this, we embarked on a thoughtfully planned extension at the rear and side of the property, ensuring that the front reception room and hallway were preserved in their original form. Additionally, we incorporated a utility area/boot room and a cozy study on the ground floor for added functionality.

Moving up to the first floor, we designed a side extension to accommodate a stunning new en-suite bathroom. And we went even further by undertaking a generous loft extension on the second floor, creating a luxurious new bedroom complete with an en-suite bathroom.

In addition to the transformations happening within the main house, we also provided a design to revamp the large garage into a vibrant playroom, complete with its very own convenience—a WC. The aim was to provide a space dedicated to amusement and entertainment for the whole family.

As we await the completion of this exceptional project, we are continuously amazed by the progress and the positive impact it will bring to our clients' lives. Stay tuned for further updates on this exciting project!

We started this project in 2017 for the client, a family of two.

The brief included a ground floor rear extension and a loft conversion to an existing terraced house in Barnes, South West London. The property fell within the Barnes Green Conservation Area.

As it often happens in these cases the challenges were not just architectural and structural. Planning in these instances can represent a potential roadblock, especially with the property falling in a Conservation Area.

The proposals were discussed with the client and then agreed with the planning officers. In this case we worked very hard with the Council proving the presence of similar precedents on the road and discussing the best design for the roof in order to be in keeping with the style of the Conservation Area. The initial proposals for a larger rear dormer was amended to allow for two smaller conservation style lead dormers that were welcome by the Council.

The property was also extended to the rear in order to form a new open plan layout with a galley kitchen opening on a patio that constitutes the only outside area of the house. In order to maximize the feel of space between the inside and the outside it was decided to have a flush threshold between the floors and use the same tiles for both the kitchen area and the patio. A set of large sliding doors also helped to create the feeling of a seamless transition between indoor and outdoor space. This project is an example of how good design can help maximize the spatial feeling even when square footage is limited.

An additional technical complication was the presence of a manhole within the existing property which had been double sealed. In order to carry out our extension and alterations we had to move the manhole to the new patio and reach an agreement with Thames Water.

We also pushed both the contractor and structural engineer to conceal the new structure within the existing ceiling to form a smooth transition between the various spaces at ground floor level.

In the end we were very pleased with the result and consider this project to be extremely successful.

First images of our new project for a loft extension in Hampton

We recently got planning approval for a loft extension project to a large detached house in Hampton. The project includes a new master bedroom, dressing area, a large bathroom and a new study opening on the extended staircase. We are now working on the detail design phase, more images will follow.

The client for this project provided Square One Architects with a brief that could be summarized as a loft extension for their Victorian 4-bedroom detached house located in the heart of Hampton and within the Hampton Village Conservation Area.

The property in question, an impressive large historic house built in the XIX century, was peculiar being detached from the neighboring property by a very narrow nominal gap.

The property had also been extended to the rear in more than one occasion and it featured a partly pitched and partly flat roof.

Unfortunately, the pitched roof did not have enough head height to form a habitable loft extension so one of the main requirements of the project from a planning perspective was to raise the ridge of the existing roof to meet the required standards.

It was agreed with the client to prepare a pre-planning application for a design that would involve raising the ridge of the existing roof and extending it towards the back. This configuration provided enough space for a master bedroom, a large bathroom, dressing area and a study.

Another request from the client was to keep the existing stair of the house as bright as possible. The presence of a very large skylight above the new stair and a large central shaft guarantees that this request is successful met.

Following the pre-planning application, the external look of the extension was slightly changed to introduce a mansard profile towards the rear and three conservation style dormers. This alteration was met very positively by the local authority that subsequently provided planning approval for the proposals.

The result is a very large loft extension that is in keeping with the character of the Conservation Area and at the same time addresses is all the targets that our clients included in the initial brief.

House refurbishment and extension in Hampton Hill completed

Our project for a house refurbishment and extension in Hampton Hill has been completed. You can check the final pictures here.

Our project for a full house extension and refurbishment in Hampton Hill has been finally completed. This was a remarkably interesting project with a client who proactively engaged in a dialogue with the Architect throughout the whole design phase.

The project started as a ground floor extension and full house redevelopment that would have eventually included a second phase with a loft extension. The client wanted a project that would consider both phases of the design at the same time to avoid any inconsistency at a later stage. As it often happens the clients plans had to change halfway and they decided to reduce the scope for the ground floor extension and carry on with the construction of the loft extension in one single phase.

Our approach has been flexible, and we redesigned parts of the project to exclude certain sections of the rear extension. The revised project included most of the internal alterations that would enhance the property as a whole in particular turning the existing stair 90 degrees to be parallel with the house.

By the end of the project, the property gained two extra bedrooms and one family bathroom at second floor level. Turning the stair 90 degrees allowed to provide a more logical layout at both the ground and the first-floor level. The stair benefits from a skylight at second floor level that provide daylight for the circulation whole space. This is a rare feature in these types of properties, and we feel that the presence of natural daylight in the middle of the house should always be welcomed.

We would like to take this opportunity to thank the client for their involvement at all stages and the contractor for building an extension that reflects our design. The construction process was overall very seamless, and this is due to the professionalism of the builders and the precision of the instructions included in our drawings package.

Construction of an extension to a house in Raynes Park has started

The construction of our project for a ground floor rear and loft extension in Raynes Park has started. The project includes some significant internal alterations to an existing semi-detached house. More images to follow.

This project for a three-bedroom semi-detached house in in Raynes Park comprised a ground floor rear extension and the loft extension plus number of internal alterations.

The clients first approached Square One Architects in 2018. The initial brief was for a rear extension that would include the larger open plan kitchen and dining area and a new, more private living space. The client’s wish list also included a small private study and a ground floor guest WC. The client also requested a new utility space at ground floor level with a washing machine and a sink.

At second floor level the client wanted to make use of their loft space by extending to the rear to form a new master bedroom and en-suite bathroom.

Square One architects was involved with the project from the very beginning. We helped the client designing the perfect space to match their needs and obtaining planning and building control approval. This project was the perfect example of how a strong and positive professional relationship between client and architect can help producing great design.

As usual we carried out a detailed analysis in terms of daylight intake and prepared precise artificial lighting layouts. The study area was placed towards the rear of the extension, with the option of making it part of the open plan or closing it with a sliding door. The same approach was used to the front reception room where a set of large sliding doors provides the options to keeping the spaces opened or more private.

As usual Square One Architects’ drawings also formed part of the contract and this allowed the contractor to provide a detailed quote.

Construction started in late 2019 and is now well underway. The final project pictures will follow shortly.

New project in Hampton

We have been appointed to develop a loft extension and a ground floor extension to an interesting 1930's bungalow in Hampton. More images will follow in the near future

The client, a family of three with one child, approached us in 2019 with an ambitions project for their two bedrooms bungalow in Hampton. Bungalows have always a great potential in terms of further development due to their usually very large footprint.

In this case the existing bungalow had been extended to the rear, however the extension was not heated and poorly built. Another issue is that the previous owner had not opened the original rear wall of the property and because of this, the original rooms facing the back of the property had lost views and daylight. This is a very typical scenario and we had to face similar situations in the past, for example in the case of our project for a rear extension in Kingston that can be seen here.

The project is divided in three phases that include a loft extension, a side extension and a rear extension. In these circumstances we usually suggest designing the whole project in one go and then extrapolate the various elements to be built in different phases.

In this instance the first stage will involve extending the existing roof of the property to form two or three new bedrooms and a family bathroom. The project also involves extending the existing roof through side dormers that will allow to achieve the necessary head height throughout the second floor.

Two apex windows, along with a number of skylights, will provide daylight to the new bedrooms and will be one of he features of both the front and the rear façade.

We can’t wait to show more detailed drawings and start construction of this interesting project.

Project schedule #2 Home extension in East Sheen

Year: 2017-2018

Location: East Sheen, London Borough of Richmond upon Thames

RIBA Design Stages: 0-5

Architect: Square One Architects

Structural Engineer: Glencross & Hudson

Building Control: Building Control Approval

The client for this project, a family of 5 with 3 small children, came to us in 2017 with a very specific brief. They had obtained planning permission using another architectural firm; however, they were not happy with the overall design.

The original project included a side extension, a rear extension and a first-floor infill extension. Despite getting planning approval for a significant additional square footage, the client was not very happy with the overall design and felt that not enough time and care had been spent in the  initial design phases (concept and schematic design) in order to agree a plan.

In this instance our first goal was to optimize the existing plan. Since the very beginning it became obvious that we would have had to go back to the planners with an amendment to the original planning application. The new plans were thoroughly discussed with the client until the layout was totally agreed.

Revised drawings were then submitted and subsequently agreed with the council. The side extension included a bedroom with a small living space and an en-suite bathroom to be used as a granny annexe for the clients’ aging parents.

The rear extension included an open plan kitchen, dining area and living space for the family.

The first-floor infill extension included a new large family bathroom (the original property was curiously lacking a shared bathroom and featured only two en-suite bathrooms).

The client also asked us to design a loft extension for the property an include a bedroom with an additional en-suite bathroom to be used by their au-pair.

The original four-bedroom house was turned into a generous 6-bedroom property with a well-proportioned family bathroom, three en suite bathrooms and plenty of open plan space to be shared with the client’s growing family. We were thoroughly pleased with the results and received a very positive feedback from the client.

The client for this project approached us in 2017 with an initial briefing that included a ground floor side return extension, alterations to the existing stair and several internal alterations to the ground and the first-floor layout.

The existing property was a typical two ups two downs terraced house in Hampton Hill. The property dated back to the late XIX century and in need of renovation. During the initial phases of the design we agreed with the client to turn the original stair by 90 degrees in order to provide a more rational layout. The initial project also included a ground floor side-return extension to form a new living and dining area to the rear and large bi-folding doors.

After obtaining planning approval for these alterations the clients’ plans changed due to their personal circumstances and they decided to add a loft extension to the project.

Sudden changes in the initial brief are not unusual and we as are always happy to accommodate any additional requirement with flexibility.

The brief for the loft extension included two new bedrooms and the family bathroom with one of the bedrooms to be used as a study or guest bedroom.

A new planning approval was obtained for the loft extension and subsequently detailed drawings were produced for both tender and construction purposes.

The refurbishment was carried out within the clients’ budget with no delays, thanks to the professionalism of the contractor, but also to the clarity of our drawings and instructions.

The result is a 4-bedroom house with 2 family bathrooms and well laid out distribution spaces that benefit from additional daylight created by a skylight that was been placed on top of the new stair.

This full house refurbishment has been a great success and we are very happy that the clients, a family of two are now enjoying their extended property.

Loft extension in Hampton given planning approval

We recently received planning approval for a large loft extension to a detached house in a Conservation Area. These projects are always challenging due to planning constraints, but working in close collaboration with the Council can lead to a very positive outcome. We are now very excited to start the Detail Design phase, more images will follow soon!

The project is for a very large loft extension within a Conservation Area and as it always happens in these cases we had to go through several steps before receiving the formal approval.

The first one was to discuss the project with our clients and agree the overall design of the extension. Following this we sent the drawings to the Council to receive pre-planning application advice.

In this circumstance the pre-planning application proved to be extremely useful. We were able to engage in a very constructive conversation with the council and agree a design that would satisfy all the parties involved.

Our initial proposal was for a very modern looking loft extension including metal cladding and large doors and windows. The project also involved raising the ridge and the eaves of the existing roof.

Given the conservation status of the area we were not surprised when we received the first feedback from the council that suggested to use a more traditional language externally. We amended the proposals to include a mansard roof and smaller traditional looking dormers facing the rear of the property. We also included several roof lights that would not be visible from the street.

In the grand scheme of things this worked very well for us because we essentially achieved the same amount of space that we initially proposed. The daylight intake that we lost by reducing the size of doors and windows to the rear was regained by using skylights placed in strategic positions.

The result will be a gorgeous open space that will take advantage of a significant head height that matches the first floor of the property and very adequate daylight intake.

We can wait to see the project build and we'll update the blog in due course

Loft extension in the Hampton Conservation Area: new video under construction

We recently visited our project for a loft extension in a Conservation Area. This video shows the transition between the new stair to landing to the new master bedroom and en-suite.

The client approached Square One Architects in 2018 with the specific brief for their three-bedroom semi-detached house in the Hampton Village Conservation Area.

The intention was to use the loft of their property as a new master bedroom with an en suite. The room would take advantage of some very interesting views to the rear towards the Hampton Water Works and unobstructed daylight.

Given the fact that the property was in a Conservation Area, we suggested the client to go through a pre-planning procedure in order to obtain an informal feedback from the Council.

This was very useful, and it helped inform a second iteration of the design that included a mansard roof and two smaller lead dormers that was deemed to be more in keeping with the existing property and the character of the Conservation Area in general.

The original stair of the property, connecting the ground floor and the first floor, was very steep and its head height was already quite limited. One of the challenges of this project was to design the new stair contacting the first floor and second floor without further compromising the already limited head height at first floor level. Thanks to a very precise 3D model we managed to foresee the exact dimensions of the new stair in relationship to the existing one and this helped tremendously our communication with building control and the stair’s supplier before and during construction stage.

This loft conversion video was taken around the end of the construction process. The room feels bright and spacious and take advantage of the generous amount of daylight from the two new windows to the rear and two large skylights installed at the front of the property. The new bathroom was installed within the eaves of the roof and it is naturally lit by one further skylight facing the front of the dwelling.

More images to follow soon.

Loft extension in Twickenham

We are currently working on an interesting project for a rather unusual loft extension. Instead of using their roof as a bedroom, the clients want to form a new sitting area with a set of large doors at the back and skylights for star gazing

The project for this loft extension to a 1930’s semi-detached house in Twickenham started in March 2019.

The clients’ brief was rather unusual in the sense that they wanted to use the second floor of their extended property as a living space for their family rather than as a bedroom as it is often the case in these types of projects.

The client also requested a large skylight and doors facing the rear of the house for stargazing with their telescope.

Following an initial discussion and consultation, the client chose an option that involved converting a small bedroom at first floor level into a full height study area that also serves as a hallway for the new stair connecting first and second floor. This is a solution that we have used in other projects. The main advantage of this option is that only one door at first floor level is required, leaving the first-floor study/hallway and the second floor completely free from any partition.

At the top of this full height space it was decided to install two large skylights facing the front of the property. The orientation of the house, with its front facing the north, will allow to gain much daylight without any major risk of overheating.

The loft extension is facing south and in this part of the house it was agreed to install external doors with a juliet balcony and a large openable flat roof skylight.

Planning approval was obtained in early 2020 and we are now working on the Detail Design for this interesting and unique project.

We look forward to seeing this project build!

House extension and refurbishment in Hampton Hill

We are excited to present our new project, a home expansion and renovation in Hampton Hill. We have a video that shows the design from start to finish, giving you a clear view of the transformation. Be on the lookout for more pictures that will showcase the skilled work and careful design that went into creating this space.

At ground floor level, our clients requested a side return extension to expand their living space. This involved the removal of an existing bathroom to make way for an open and inviting area that encompassed both a new kitchen and a dining area. Additionally, one of the main design challenges we tackled was the reorientation of the existing staircase by a 90-degree angle within the new kitchen/dining space.
Moving up to the first floor, we transformed one of the bedrooms into a generously proportioned bathroom. By removing an existing partition, we successfully fashioned a second spacious bedroom on this floor, maximizing the available space to meet the needs of the family.
Expanding further at the loft level, we introduced two brand-new bedrooms and a family bathroom. This addition not only complemented the existing layout but also provided our clients with an accommodating and versatile space for their growing household. We took great pleasure in designing this project specifically tailored for a young couple, and we have full confidence that the thoughtfully crafted spaces will cater perfectly to their evolving needs.

Loft extension in the Conservation Area in Hampton Village

Check out our new video of a loft extension project in Hampton Conservation area. See the construction progress and attention to detail as the extension comes together. This addition includes a spacious landing area, a beautiful master bedroom, and a luxurious en-suite bathroom. Watch as this empty space is transformed into a modern yet charming design.

The client initially approached Square One Architects back in 2017 with the exciting project of extending their charming 3-bed semidetached house in Hampton. This property, situated within the Hampton Village Conservation Area, held great potential for an expansion. With a vision to create a spacious haven, the client specifically wanted to extend the loft area to craft a master bedroom complete with an en-suite bathroom.
Upon examining the property, we discovered that it already featured an existing gable roof, which conveniently provided an internal height of approximately 2.8m. This height proved sufficient to accommodate our proposed loft extension, sparing us the need for major alterations to the ceilings below. With this positive starting point, we engaged in extensive discussions with the client regarding the planning strategy for their renovation.
Considering the property's location within the Conservation Area, we mutually agreed to take a proactive approach by submitting a pre-planning application. This strategic move allowed us to seek preliminary feedback from the Council, ensuring our design aligned seamlessly with the neighborhood's rich architectural heritage. By involving the local authorities early on, we could streamline the planning and approval process, thus reducing potential delays.
To optimize space utilization within the property, we strategically positioned the new staircase for seamless connectivity between the first and second floors. By aligning it with the existing stairway, we minimized any unnecessary loss of space at the first floor level. This thoughtful design solution ensured that the loft extension harmoniously blended with the existing layout, enhancing both practicality and aesthetic appeal.
At Square One Architects, we pride ourselves on crafting solutions that not only cater to our clients' desires but also effectively navigate local regulations. This project in Hampton embodies our commitment to preserving the architectural integrity of heritage areas while tastefully elevating the living experience for homeowners.
