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!

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.

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: House extension in Kingston

First image of our new project for a rear extension in Kingston

Square One Architects have been appointed to redesign the rear extension of a large XIX century semi-detached house in Kingston.

The property in question was extended in 2003 by the previous owners however the clients were not happy with the overall design.

Their main complaint regarded the amount of daylight that they received within the ground floor of the property and the connection between the extension and the rest of the house. In fact, the existing extension was separated from the original rear of the property by a thick wall with two small openings causing the original rooms facing the back garden to be extremely dark.

This is very typical situation. Extending traditional properties without any consideration given to daylight intake always carries the potential risk of creating spaces that feel dark and separated.

The clients’ brief included the removal of the non-original extension and replacement with a new one that would allow a generous amount of daylight throughout the ground floor of the property. They also wanted to carry out some internal alterations that would allow to have a seamless connection between the existing spaces and the new extended section of the house.

The project also included moving the existing kitchen to the new open plan area, using the original kitchen space as a playroom.

As a practice we felt that we were the perfect match for this type of project given our expertise in residential design with a focus on the south west of London and our specialist expertise in lighting design.

The layout shown in the drawing above exemplifies our ideas for this project where the internal space formed by the existing house and the new extension feel like one.

A set of sliding doors, two large roof lights and a spectacular l-shaped window to the opposite corner will allow for daylight to be distributed throughout the floor plan.

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.

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.
