This project was for an extension to a large detached house in Byfleet and New Haw for a family of three with a small child.

When the client got in touch with us in first instance, we visited the site and found that the house needed a renovation. The client was also not satisfied with the ground floor arrangement that was very partitioned and formed rooms that where both small and dark.

At first floor level the layout was more acceptable, however the house lacked the presence of a real master bedroom with a dressing area and an en-suite bathroom, which is something that you would expect from a property of this size.

Our brief was to extend a house with a rear extension and form a new open plan layout including a kitchen, dining area and sitting area. The client also requested a first-floor side extension on top of an existing garage that would provide space for an en-suite bathroom and dressing area linked to an existing bedroom.

We considered two options for the existing garage. The first one was to retain it and build on top of it and the the second one was to demolish and rebuild. As it often happens in these cases the option to replace the existing garage ended up being more cost-effective. It is not unusual to find period structure that are not able to carry any extra load from a structural point of view, especially at foundation level. In these instances, we always suggest our clients to hire a builder for a couple of hours, perform several trial pits and then submit the results to a structural engineer that will decide whether the existing structure is suitable or not. All the details will then need to be confirmed with Building Control.

The ground floor rear extension also features a set of large bi-fold doors that opens towards the rear garden and a window in correspondence of the kitchen sink. A set of two large flat roof lantern skylights also help bringing daylight in the new open plan area.

The first-floor side extension also features rear and front windows and a large skylight that guarantees uniform levels of daylight throughout the whole floor plan.

The clients’ feedback was very positive, and we appreciated hearing that they used their new spaces in a more practical way with their toddler always in sight. That's a big advantage of open plan layouts!

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.

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.

Work in progress: House extension in Kingston

Another view of the preliminary design for a ground floor rear extension to a semi-detached house in Kingston. The intent is to integrate the existing window and chimney breast with the new kitchen, creating a low window seat that can be enjoyed by the family.

In this view we tried to highlight the relationship between the kitchen area to the left and the open plan dining space to the right. The seamless ceiling transition helps to make these two spaces feel connected and cohesive from a design perspective.

The same floor will be used for both the existing floor plan and the new extension, leaving the two structural piers as the only demarcation between the original rear of the house and the extended portion.

An interesting feature of the existing house is the presence of a side window that is our intention to turn into a window seat that will feel like an extension of the kitchen itself.

Window seats are a fun feature that help creating some interesting corners that can relate to other elements of the room, in this specific case the kitchen island and breakfast bar right in front of it.

The kitchen, island, window seat and the extension’s window and skylights will all contribute to create an interesting space to be lived by our clients.

Another image of our new project for a rear extension in Kingston featuring an open space kitchen/living/dining

This image highlights a very important design feature that is often overlooked, the seamless ceiling transition between the existing house and the new extension.

From a design perspective this is an ideal solution when we are dealing with flat ceilings with an identical head height. The lack of any beam or bulkhead separating the spaces creates the feeling of a cohesive space with one unobstructed ceiling. The other major advantage of this type of solution is that daylight coming from the skylights in the new extension does not get blocked by any obstructions at ceiling level. This guarantees optimal daylight distribution within the floor plan.

There are some structural implications with this type of solution that need to be assessed by qualified engineers and architects and discussed with he builder, however the end result is always wotlrth the effort. In the case of this project in Kingston the open plan will feel bright and spacious with a cohesive design that will give the impression of a very natural space that was always meant to be there.

We can’t wait to see this project finished and show how effective this solution can be through the final pictures. In the meantime you can see another project for a rear extension where a similar solution was adopted by clicking here.

Work in progress: rear and loft extension in Hampton

We want to show you a beautiful picture of our latest project in Hampton. It's an extension at the back and on the top floor of a house. The picture shows a modern and impressive design with a lot of attention to detail. In the picture, you can see a playroom, a dining area, and an open plan kitchen. The design makes the space flow smoothly, which is great for relaxing and socializing.

At Square One Architects, we take pride in being able to explain our design ideas clearly to our clients. We often use 3D modelling tools to help our clients understand and appreciate our designs. These tools allow our clients to experience their future homes in a virtual way. This advanced technique makes it easier for our clients to imagine their dream homes. With our expertise in 3D modelling, we make sure to include a lot of detail and make everything look realistic. This helps our clients form a strong connection with their imagined spaces.

3D modelling comes particularly handy following the planning stage when clients are expected to take important decisions on their projects, such as materials, kitchen design, lighting, and many more. Utilizing 3D modelling technology allows architects to present clients with a variety of options in quick succession, enabling them to visualize the different possibilities with ease and make well-informed decisions. The ability to present multiple designs efficiently not only saves time but also enhances collaboration between the architect and the client, ensuring that the final outcome meets the client's expectations and preferences. By harnessing the power of 3D modelling, architects can bring ideas to life, enabling clients to make informed choices and ultimately leading to the creation of stunning, functional spaces.

Render vs completed photo of our latest house extension in Byfleet & New Haw

It's always interesting to look back at the design and evaluate how the final product compares to the initial intent. In this image a photo realistic render (above) is compared to a final image of a kitchen space.

It is always essential to keep track of the relationship between designed spaces and final build project in order to verify the validity of our vision and take note of what has been improved during construction or what could have been built differently.

In the case of this project for or a rear and side extension to detached house in Byfleet and New Haw we were pleased to see that our 3D model rendering (first image above) looks very similar to what the contractor delivered on site.

First and foremost, the size of the openings and the subsequent amount of daylight received by the internal spaces was correctly predicted by the virtual analysis carried out through the rendering engine. Second, the materials that the client had chosen where confirmed to be a good match for the type of space that we had designed.

This project proves once again that 3D modelling and rendering tools can provide an invaluable help to both the Architect and the client.

By using these tools, the Architect can convey an idea in a very straightforward manner and the client can understand it right away, taking the necessary decisions when requested by the Architect.

We feel that the best stage to provide this type of drawings to a client is detail design where decisions about materials and certain technical details need to be finalised. Although there is a benefit in producing preliminary 3D models at earlier stages of the design, we see little point in generating super realistic images without any decision being made by the client regarding large items such as finishes, kitchen etc…

new haw project now completed

Our project in New Haw is finished - we've successfully completed a rear extension and first floor side extension for a large detached property. The carefully designed additions seamlessly blend with the existing structure, improving both its function and appearance. The rear infill extension provides a lot of space for a modern living area, great for hosting guests or spending time with family. The first floor side extension adds extra rooms for bedrooms or a home office, providing flexibility for the homeowners' changing needs. The completion photos show the impressive transformation, displaying the attention to detail and high-quality workmanship that went into the entire project.

As architects at Square One Architects, our dedication to lighting design is always at the forefront of our work. We understand the importance of both natural daylight and artificial lighting in creating spaces that not only look stunning, but also enhance the overall well-being of those who inhabit them. From the moment we begin a project, we carefully consider how to maximize natural light, allowing it to filter through strategically placed windows and skylights, while also incorporating innovative artificial lighting solutions. The photos showcased here serve as a testament to our commitment as a practice to design spaces that are not only well ventilated and bright, but also transform the quality of life for our clients, allowing them to thrive in spaces that inspire and uplift.

House in Byfleet and New Haw coming soon

Sneak peek: a video of a photo shoot for our project of a house extension in Addlestone. Pictures coming soon!

The client initially reached out to Square One Architects in early 2018 with the exciting opportunity to expand their 4-bed detached house in Byfleet and New Haw.

Seeking to enhance their living space, the client's brief entailed the construction of a new kitchen diner that would seamlessly merge with the existing layout. In accordance with the client's vision, the ground floor would be extended by approximately 2.5m to the rear, allowing for a spacious and inviting open plan area.

Throughout the design process, the integration of the extension's roof with the existing structure was carefully considered to ensure a harmonious and unified aesthetic. Additionally, the client expressed a strong desire for bi-fold doors at the back of the extension, along with strategically placed skylights to flood the new open space with abundant natural light.

To further cater to the client's needs, the project also encompassed a first-floor side extension, facilitating the creation of a luxurious master bedroom complete with a dressing room and en-suite bathroom.

Our latest project in Teddington

You can take a look at our most recent project showcasing a side and rear extension in Teddington by clicking here. This extension not only enhances the existing home but also creates additional functional space for the homeowners.

The client initially approached Square One Architects in 2017 with a vision of expanding their 3-bed semi-detached house in Teddington. With a desire for both a side and rear extension, it was clear from the outset that removing an underutilized and dilapidated garage would be necessary. By eliminating this underused structure, an opportunity arose to create a generous 6-meter deep extension to the rear. Additionally, the ground floor was extended by approximately 2 meters to the side to incorporate a convenient utility room, study and guest WC. Retaining direct access to the rear garden was made possible by a narrow passageway created on the side of the property.
While the client had initially expressed an interest in extending the loft as well as the ground floor, a deliberate decision was made after careful consideration to postpone this segment of the project. However, in 2021, Square One Architects successfully completed the loft extension, bringing a project that initially commenced four years ago to its fulfilling culmination.

Project in Hampton under construction

The ground floor extension depicted in the initial images showcases Square One Architects' intricate design approach for a grand detached 1930s house in the Hampton. The primary objective of the client was to fashion a vast, unobstructed area that seamlessly blends with the charm and essence of the original structure, transforming the space into a cohesive design.

The client approached us in 2017 with a project for an extension of their beautiful 1929 detached house situated in Hampton. The initial brief was to transform the existing conservatory into a stunning solid wall extension that would perfectly align with the house's current footprint. As part of this extension, we proposed the idea of opening up the east facing walls in the dining room, not only to enhance circulation throughout the ground floor but also to establish a captivating visual connection with the beautiful garden outside. Understanding our client's desire to brighten up the existing house, we dedicated ourselves to significantly improving its intake of natural daylight.
To further enhance the functionality of the house, we also designed a side extension, forming a brand new and invaluable utility room. Upstairs, our team focused on remodelling the existing family bathroom, elevating its overall design and functionality.

Our latest project in Twickenham

If you're looking for inspiration for a rear extension project in Twickenham, you won't want to miss our latest work! We invite you to take a closer look at our recently completed project, which showcases our expertise in thoughtful design and seamless integration. Located in Twickenham, this rear extension seamlessly extends the living space of our client's home, creating a harmonious blend of indoor and outdoor areas. Discover how our innovative approach to architecture has transformed this property, combining functionality with aesthetic appeal.

We started this project back in 2016 when the client approached us with an idea to extend their 2-bed semi-detached terrace in Twickenham. The clients already had planning approval for a single-storey rear extension, but they were not satisfied with the design approach of their previous consultant. Thus, they came to us seeking our creative input to maximize the potential of their available space.
One of their main concerns was to reconfigure the internal layout of the entire ground floor to create a more seamless and functional flow for their family. They wanted ideas and suggestions on how to improve the utilization of each area. Considering their requirements, our team produced a comprehensive feasibility study showcasing several design options.
With the feasibility study in hand, we engaged in discussions with the clients and presented our findings. They were pleased with the options we provided and expressed their willingness to submit an amendment to the previous planning drawings. This was an important step towards realizing their vision and enabled us to proceed with the subsequent design phases.

These captivating photos capture the essence of our client's vision and determination, alongside our meticulous approach to architectural design. Each image tells a story of collaboration and creativity, showcasing the fusion of the client's aspirations and our team's expertise.

Rear extension in Twickenham

First image of our new project for the rear extension of a semi-detached single family house in Twickenham!

The rendering above shows our initial proposal for our 2016 project of a rear extension to a terraced house in Twickenham. The property in question was semi-detached and featured a non-original, very narrow and poor-quality built rear extension that used to house the kitchen and did not take advantage of the full width of the plot.

The client’s wish was to form a new open plan kitchen and living area opening towards the rear garden with the kitchen in the middle of the extended house.

The position of the kitchen in relation to rear extension is an important element and it comes down to individual preference. In some cases extensions are wide enough to house both kitchen and dining or living area to the rear like in the case of our house extension in Teddington and many other examples on our project page, however in some cases the existing house is just too narrow and just one between kitchen and dining area can be housed a the rear.

Some families tend to use the kitchen as a very social space, in which case it may make sense to place it towards the rear with the best views of the garden, access to daylight and connection with the patio.

Some others see the kitchen as a less social space and prefer to place a dining area or living space at the rear. This is something worth thinking long and hard before taking a final decision.

In this case the client decided to place the kitchen in the central section of the property. In this configuration it is very important to design the kitchen as a feature and keep it very tidy since you will always move across the kitchen to go from the front of the house to the rear. This is one of the reasons why the client asked us to design the kitchen from scratch in order to ensure that the design quality was consistent throughout the whole ground floor of the property.

We have to give credit to the clients for their commitment to good design. We enjoyed the overall design process and were very pleased with the final result..

New project in Twickenham

Square One Architects have been appointed for the project of a conversion a small coach house to a residential home in the town center of Twickenham.

Our client, a small developer, looked for several firms of residential architects in Twickenham and chose Square One architects to carry out the project for this conversion.

The overall brief is simple; the client is looking to convert an existing coach house to a one-bedroom house organised on two levels.

The initial idea was to dedicate the ground floor level to kitchen and living space including a bathroom. In this configuration the first floor of the property would then be used as a bedroom with a Juliet balcony opening towards the small alleyway.

After an initial discussion, it was been decided to move the living area to the first floor due to the availability of natural daylight and better views.

The one double bedroom of the house will be located at ground floor level with direct access to a bathroom that partly used the space under the stairs.

Square One Architects’ design and careful lighting consideration will help to make the most out of a very limited amount of space!
