In this schedule we will revisit a project designed in 2018 for a rear extension in Hampton.

This was a very fun project for a young couple and their lovely dog. The existing house was a typical terraced property that had been extended at loft level.

The ground floor of the house also featured a rear extension probably from the 1980’s. The extension had been poorly built at designed and needed renovation. This is a very typical scenario, house extensions built in the 80’s are often mediocre construction with hardly any insulation and poorly performing windows.

In this case the rear extension was also not making the most out of the full width of the site leaving a side-patio that was essentially wasted space.

Internally an opening had been created between the reception room and the rear. More and more clients are asking us to revert these types of feature. The front reception room was usually designed to create a buffer between the street and the more private rear of the house and people are starting to appreciate this feature more and more.

Our project targeted all the problems highlighted above with a new rear extension that included a bright kitchen and dining area and a new WC and utility room in the darker section of the ground floor.

We analysed daylight carefully in order to provide as much natural daylight to the extension as possible. The before and after pictures speak for themselves.

The clients’ feedback was great, they felt the ground floor had been resolved with a rear hallway leading to the ground floor WC (separated from the rest of the living and dining areas). The rear extension features large skylights and Crittall style French doors and window (supplied by Fabco Sanctuary). They also appreciated having a very private front room.

The result is a very practical layout with an open and bright living area that the clients will certainly enjoy in the years to come.

This project for a rear extension in Hampton Hill dates to 2016.

The clients, a retired couple, asked us to extend their property to the back. The existing house was a typical 1930’s semi-detached dwelling with a large garden to the rear. The clients’ initial brief was for a straightforward three meters rear extension with some internal alterations that would allow them to have an open plan layout, however they had an additional request: to retain a sunny corner in their outdoor patio. This led to the decision to design a three meters rear extension built under Permitted Development that would not use the full width of the rear garden in order to retain the sunny corner that our clients loved so much.

In order to highlight this design intention, we proposed to have an L-shaped window that would provide views to the rear garden and to the side patio at the same time. A set of large French Doors was then designed to allow access to the site patio. The client was also very keen to use triple glazed Swedish windows and chose West Coast Windows as their supplier.

It was agreed with the client to have a flat roof extension reminiscent of the 1930’s minimalist approach that would create a nice contrast with the existing style of the house. In order to highlight this minimalist approach, we concealed all the rainwater pipes within the new walls.

The same logic informed the materials inside the extension where a herringbone wood floor was chosen for both the existing and the new section.

As we always do, we simulated the amount of daylight that the extension would receive depending on the moment of the year to guarantee that the new new space would be very bright at any moment of the year without any overheating.

The result is an extension that enhances the existing building and is very cohesive in terms of interior design with the rest of the property. In this circumstance we worked with an interior designer who happened to be our clients’ daughter in terms of internal materials and color palette. It was a very successful project that pleased all the parties involved.

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.

Crittall style doors for a project in Hampton

We love Crittal style doors and windows. In this instance the doors were supplied by Fabco Sanctuary

For the second time in a row we used Crittall style doors and windows supplied by Fabco Sanctuary for a project of ground floor rear extension in Hampton.

In this instance the client approached us after having seen our project for a rear extension in Teddington and asked to use the same type of doors that had been used in that instance. We were very glad to adopt the same solution for this project because we are big fans of these types of steel doors and windows that maximize daylight and views thank to their thin frames.

Crittall doors and windows have a long history in Britain. These types of steel doors and windows frames have been fabricated since the 1930’s. Crittall remains one of the most important manufacturers of these steel doors and windows, however there are several other companies that provide competitive “Crittall style” frames.

Modern thermal requirements meant a change in the design of the frame to include double glazing and thermal breaks.

Despite not being the most thermally efficient doors and windows on the market these types of frames manage to achieve levels of transmittance that are generally accepted by building control.

We feel that the industrial look of these doors and windows along with the simple lines of a minimal white flat roof extension provide character and contrast to extensions carried out for houses that date back to the 1930`s or similar period.

The project has been now completed and the final pictures can be seen here.

Project schedule #3 Rear extension in Teddington

This project for a rear extension in Teddington dates to 2017. The clients, a family of four with two small children, approached us asking for a complete remodeling of the ground floor of their house that would include a side extension and a large rear extension. The idea was to integrate within the existing spaces and in the new extended spaces a guest WC, a utility room, a small home office and a large open space to include a generous kitchen a dining area and a sitting area. The presence of some large rear extensions in the properties nearby served as a precedent in terms of planning. It's always very important to look around your property and see what your neighbors have built in the past. The rule of thumb is that if planners gave approval for an extension recently that precedent should be used to support the new application.

The product is characterized by large glazed surfaces including several flat roof skylights, two sets of French doors and a large window in correspondence on the kitchen area. The client was adamant to avoid having large bi-folding doors to the back, they wanted their extension to feel unique and to integrate traditional elements in its design. It was agreed to use Crittall style steel windows reminiscent of the 1930`s design. It was also agreed to leave some steel beams exposed. In these cases, any structural element needs to be treated with specific intumescent paint in order to avoid any fire hazard. This type of details was agreed with building control before the beginning of construction.

We are extremely pleased with the result and the client provided a wonderful feedback. The simple lines of the new extension are in keeping with the relatively straightforward design of the rear of the existing 1930’s house.

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.

We are really pleased with these Teddington house extension photos by Emanuelis Stasaitis.

He is always very good at getting the best shots out of our projects and I think these home extension photos prove the point.

This home extension in Teddington was designed between 2017 and 2018 for a young family of four with two children.

It was it was a great experience from our point of view because the clients proved to be informed and engaged from a design perspective at any stage.

The project involved the ground floor side and rear extension and complete remodeling of the floor plan.

The existing property was a typical 1930s semi-detached house with large garden at the rear. As it often happens the property had been extended in the past with a conservatory that used to be too hot in the summer and too cold in winter.

The initial client idea was to demolish the conservatory and carry out a rear extension however it soon became apparent that adding a side extension (to match the one in the neighboring property) would have provided a very useful amount of internal space for service rooms such as a guest WC a utility room and a small study.

The client had an interest into industrial architecture, and it was decided to keep one of the structural steel beams visible. In these cases, it is essential to use an intumescent paint for fire rating purposes. We agreed with the client to retain the beam that subdivides the dining area from the living space in order to create a feature.

The client also decided to supply Crittall style doors and windows that help define the character of the extension.

Hopefully these photos will be able to inspire potential clients or provide some home extension ideas.

Rear extension in Hampton Hill

Works for a rear extension in Hampton Hill are under way. The extension includes a flat roof rear section and a pitched roof side-return.

This blog entry refers to our project for a rear extension on a terraced house in Hampton Hill, for our project of a rear extension to a semi-detached house in Hampton Hill click here.

The project is an excellent example of a rear extension built under permitted development for larger home extensions.

This 2017 project included a ground floor rear extension and side return to a 3-bed terraced house in Hampton Hill. The project also included a loft extension to form an extra bedroom and a new bathroom.

Following an initial design meeting it was decided to relocate the kitchen area to the existing dining room and se the new bright extension as a new dining and sitting area.

During the schematic design phase, we agreed with the client to have a pitched roof for the side return and a flat roof for the rear extension. A large window was in correspondence of the rear extension to form a window seat serving the dining table.

The schematic design also included a daylight analysis that informed us of the optimal size and location of doors, window and skylights above both the rear extension and the side return section.

The design was discussed with the clients and the planning officer and it was agreed to submit a prior approval application for a larger home extension. The application was approved in April 2018 and allowed the project to proceed to the next stage, Detail Design.

During this phase we defined with the clients several details like finishes, artificial lighting etc… and we also liaised with Building Control and the Party Wall Surveyor. This allowed to start construction shortly after.

Small extension in Hampton

Today we visited a small rear extension in Hampton we recently designed. More pictures to follow!

The project for a rear extension to a 1960’s semi-detached brick house in Hampton has been completed.

The existing property had been extended approximately 20 years ago go with a conservatory that used to be too hot in the summer and too cold in winter, as it often happens in these cases.

The clients’ brief was to remove the conservatory and build a new rear extension to match the existing conservatory in terms of footprint.

The rear extension was built under Permitted Development however its design was very different from the original volume of the old conservatory.

in order to provide the feeling of a more seamless transition between the existing spaces and the new one it was decided to design a flat roof extension that guaranteed a flat ceiling with the same height of the existing one.

This created a visual connection between the existing kitchen space and the new extension that was going to be used as a dining area.

Daylight was very important for our clients and one of the main points in their briefs was that they enjoyed the generous amount of light that they received through their conservatory and although they were ready to loose part of it, they still wanted to have a very bright extension.

The project also included a new side window to provide daylight and views to an existing playroom.

We ran a daylight simulation in order to finalize the position and size of the skylight, windows and French door.

Both us and our client were extremely happy with the result and the build extension confirmed what we had foreseen through our drawings.

“Iacopo is everything you want in an Architect. Talented, thoughtful, precise, punctual and fantastic value for money. He listened carefully to our specification, guided us when we were lacking in knowledge and responded incredibly well when we changed our minds. He took our ground floor extension from a pipe dream to a design in weeks, his skill set enabled the design to go through local planning at the first time of asking. He held ours hands whilst we chose the building company to complete the work. We literally could not be happier with Iacopo - brilliant!”

Rear extension in Wimbledon

We have recently visited one of our projects on site which involves a rear and side extension to a large 1930's house in Wimbledon. The transformation of this home is truly remarkable. The new impressive kitchen/living space is not only bright and spacious, but also beautifully designed to seamlessly blend with the existing structure. The large windows flood the area with natural light, creating a warm and inviting atmosphere. As we toured the space, we imagined the homeowner joy when she can enjoy their new surroundings. The open kitchen and living area is great for gathering and entertaining, and the view of the garden adds a peaceful touch. The project's outstanding outcome is a testament to the commitment and collaboration of the entire team. Each member brought their skills and expertise, working together to overcome challenges and deliver great results. The client played a crucial role in driving the project forward with determination and a clear vision. Her effective communication and enthusiasm pushed the team towards success. The synergy between our team and the client's enthusiasm led to a project that exceeded expectations.
Our team of architects have been working hard to turn the client’s vision into reality. Once everything is perfect, we'll share captivating photos of the project. Stay tuned for the big reveal, where you can take a visual journey through this remarkable undertaking that will captivate and inspire you. Stay tuned for more updates!
