First images of our new project for a loft extension in Hampton

We recently got planning approval for a loft extension project to a large detached house in Hampton. The project includes a new master bedroom, dressing area, a large bathroom and a new study opening on the extended staircase. We are now working on the detail design phase, more images will follow.

The client for this project provided Square One Architects with a brief that could be summarized as a loft extension for their Victorian 4-bedroom detached house located in the heart of Hampton and within the Hampton Village Conservation Area.

The property in question, an impressive large historic house built in the XIX century, was peculiar being detached from the neighboring property by a very narrow nominal gap.

The property had also been extended to the rear in more than one occasion and it featured a partly pitched and partly flat roof.

Unfortunately, the pitched roof did not have enough head height to form a habitable loft extension so one of the main requirements of the project from a planning perspective was to raise the ridge of the existing roof to meet the required standards.

It was agreed with the client to prepare a pre-planning application for a design that would involve raising the ridge of the existing roof and extending it towards the back. This configuration provided enough space for a master bedroom, a large bathroom, dressing area and a study.

Another request from the client was to keep the existing stair of the house as bright as possible. The presence of a very large skylight above the new stair and a large central shaft guarantees that this request is successful met.

Following the pre-planning application, the external look of the extension was slightly changed to introduce a mansard profile towards the rear and three conservation style dormers. This alteration was met very positively by the local authority that subsequently provided planning approval for the proposals.

The result is a very large loft extension that is in keeping with the character of the Conservation Area and at the same time addresses is all the targets that our clients included in the initial brief.

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.

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.

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.

Loft extension in Twickenham

We are currently working on an interesting project for a rather unusual loft extension. Instead of using their roof as a bedroom, the clients want to form a new sitting area with a set of large doors at the back and skylights for star gazing

The project for this loft extension to a 1930’s semi-detached house in Twickenham started in March 2019.

The clients’ brief was rather unusual in the sense that they wanted to use the second floor of their extended property as a living space for their family rather than as a bedroom as it is often the case in these types of projects.

The client also requested a large skylight and doors facing the rear of the house for stargazing with their telescope.

Following an initial discussion and consultation, the client chose an option that involved converting a small bedroom at first floor level into a full height study area that also serves as a hallway for the new stair connecting first and second floor. This is a solution that we have used in other projects. The main advantage of this option is that only one door at first floor level is required, leaving the first-floor study/hallway and the second floor completely free from any partition.

At the top of this full height space it was decided to install two large skylights facing the front of the property. The orientation of the house, with its front facing the north, will allow to gain much daylight without any major risk of overheating.

The loft extension is facing south and in this part of the house it was agreed to install external doors with a juliet balcony and a large openable flat roof skylight.

Planning approval was obtained in early 2020 and we are now working on the Detail Design for this interesting and unique project.

We look forward to seeing this project build!
