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 #1 Full house refurbishment in Hampton Hill

Project schedule

Location: Hampton Hill, London Borough of Richmond upon Thames

Building Control Approval

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.

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.
