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.

Rear extension in Hampton under construction

We recently visited the construction site of our project for a rear extension to a large detached house in Hampton and we were impressed by the quality of the open space and the amount of daylight received internally. The project is well underway, and we will shortly share the final pictures.

We recently went on site to see the progress for this large rear extension to a 1930s detached house in Hampton.

The existing house featured a non-original conservatory to the rear that did not address the client’s requirements. Our initial brief included the construction of a six meters rear extension that would include the kitchen, dining and sitting area. The project would also include a utility room a coat storage and a small guest WC.

The client had several other requirements, in particular the kitchen needed to have its own character and the overall architecture of the extension would have to reflect any changes in the internal layout. Another requirement was for a flush threshold between the inside and the outside in order to have a seamless transition between the new indoor space and the rear garden.

In order to provide a specific character to the kitchen it was agreed with the client to split the rear extension into two sections with the first one characterized by flat roof and the second one, above the kitchen, characterized by a pitched roof. This created an interesting rear elevation that reflected the changes in the internal layout as per our client’s request.

The project obtained planning approval in early 2019 and after that we worked with the client in order to achieve a fully detailed tender package that would be priced by several contractors. The winning contractor started works in late 2019 and the project is now almost completed.

Our site and confirmed that the strategy of having two separate roof construction types created an impressive space that feel bright and spacious, with its own strong character and with incredible views on the beautiful rear garden of the property.

Penthouse in Walthamstow: terrace

The penthouse for this project of a multi-storey residential building in Walthamstow represents one of the highlights of this project.

Set on the 5th and 6th floor of the building, the penthouse design was the initial reason why the client approached us in first instance.

The initial idea was for Square One Architects to be involved in the redesign of the internal layout of these two floors. With time the project scope became larger to include the other floors off the property.

Our contribution to the project included the rationalization of the internal floor plan in order to include a large kitchen and dining area, two generous bedrooms including a master bedroom and a large family bathroom.

The internal stair led to the 6th floor where the main living space of the property could be found. From here large glazed surfaces provided both daylight and access to a very spacious terrace with a glass balustrade.

The terrace looks really stunning and the views across this part of London are truly unique. You can see the rest of this project`s pictures here.

Multi-storey residential building in Walthamstow

We are excited to announce that a beautiful residential building has been finished in the lively neighbourhood of Walthamstow. This achievement is a significant milestone for the architectural landscape of the area. At Square One Architects, we were involved in designing the interiors and lighting for nine stunning flats within this building. We paid close attention to detail and focused on creating spaces that are both modern and functional. Each flat is elegant and sophisticated, with a seamless flow and a combination of natural light and carefully selected materials that enhance comfort and create a peaceful atmosphere.
Furthermore, our team has gone the extra mile to design spaces that meet the different needs and preferences of potential residents. Whether you're looking for a small and comfortable apartment or a large and luxurious penthouse, each flat provides a special and customized experience that suits modern city living. We've carefully thought about every aspect, from the modern and attractive kitchens to the lavish bathrooms, to guarantee a perfect blend of style and practicality.

The photo below shows the stunning penthouse, highlighting its carefully designed interior. Every part of the space fits together beautifully to create a perfect balance between luxury and comfort. The penthouse has a calm and timeless beauty, with a consistent colour scheme and plenty of natural light flowing in through the large windows.

Below is an image of the large and stylish kitchen in the new penthouse in the neighborhood of Walthamstow. The kitchen has a modern design and appliances, making it a great place for cooking. In addition to the beautiful interior, the kitchen offers stunning views of the city and nature, creating a peaceful atmosphere while you cook. The kitchen is designed to be both practical and beautiful, making cooking a pleasant and inspiring experience for the lucky residents of the penthouse.

Project schedule #2 Home extension in East Sheen

Project Schedule

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.

Planning approval for one of our projects in Hampton

We are excited to announce that we have received approval to redesign a semi-detached house in Hampton. The project includes making changes inside to improve how the space works and looks. We are also thrilled to add an extension on the back of the ground floor, giving our clients more room and a better connection to the outdoors. A new extension in the loft will also be added to create a cozy retreat.

The strategic north-facing orientation of the back of the house presents an ideal opportunity for us to capitalize on the abundant natural light, as we can confidently design and incorporate expansive glazed surfaces without worrying too much about the potential negative effects of overheating.

We are now entering an important part of the project - the detailed design phase. This is when the project takes its final shape and gets ready for construction. During this phase, we will work closely with our clients, helping them make decisions on things like materials, lighting, windows, and more. These decisions will be carefully included in the final design, so that it matches what the clients want. The detailed design phase is a big step towards making the project a reality.

We can't wait to start working on this amazing home for our clients in Hampton.

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 Project: Home Extension in East Sheen

Check out here our new project for a major redevelopment of a charming single family house in East Sheen. With a focus on preserving the character and enhancing the functionality of the existing structure, our team at Square One Architects has undertaken a comprehensive renovation to create truly spectacular spaces.

The client's commitment to this project has been unwavering, serving as a driving force behind its success. From the very beginning, they demonstrated a deep understanding of the project's vision and goals. Their active involvement in the decision-making process and their eagerness to collaborate with all the consultants has been instrumental in ensuring that the project moves forward smoothly. Constant dialogue between the client and the consultants has fostered a strong sense of teamwork and allowed for the exchange of ideas, resulting in more innovative and effective solutions. This open line of communication has not only strengthened the relationship between the client and the consultants but has also led to a higher level of coordination and a deeper understanding of the project from all parties involved. The client's commitment, combined with continuous dialogue, has undoubtedly been a key ingredient for the success of this project.

We're excited to share that our year-long project is now finished. It's been an incredible journey of creativity, innovation, and teamwork. Today, we're releasing photos that show the amazing result of our hard work. These photos highlight our vision and attention to detail. We're very proud of the outcome, which reflects the synergy and passion of our team.

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..
