What is a kitchen extension in London?
A kitchen extension in London is a building project that increases the size of your existing kitchen by extending the footprint of your home, most commonly to the rear of the property, or into a side return where space allows. It is designed to improve how the kitchen works day to day by creating more usable floor area for cooking, dining, storage and circulation, and by allowing a more efficient layout than the original room often provides.
In many homes, especially terraced and semi detached properties, the existing kitchen in London can feel narrow, enclosed or disconnected from the garden. A well designed kitchen extension enables you to reconfigure the space to suit modern living, often creating a larger kitchen dining area with improved natural light and a stronger relationship to the rest of the ground floor. When planned properly, a kitchen extension can feel like a natural continuation of the home, balancing practicality, comfort and long term value.

How we design kitchen extensions at Salstan Architecture
At Salstan Architecture, our approach to kitchen extensions is centred on creating a space that feels natural to your home, works effortlessly day to day, and is properly resolved for planning and construction. We start by understanding how you live now, what is not working in the existing kitchen, and what you want the extended space to achieve, whether that is an open plan kitchen diner, a better connection to the garden, more storage, or improved flowthrough the ground floor.
We then develop a design that balances practicality and aesthetics, with careful consideration of natural light, layout efficiency, proportions, and materials. For terraced and semi detached homes, we pay particular attention to side return opportunities, neighbour relationships, privacy, and how the extension sits within the character of the property. Every kitchen extension design is progressed with buildability in mind, including coordinated drawings and clear technical detailing, so the project can move smoothly from design to site.
Where required, we guide you through planning permission and approvals, and we keep the process straightforward, responsive, and well managed from the early concept stage through a build ready package. The result is a kitchen extension that is not only visually strong, but genuinely improves how your home feels and functions.

What our clients say about us
Lambros McKenzie2026-06-15Trustindex verifies that the original source of the review is Google. I have used Salstan on two projects now and both times they have been excellent with clear communication and quick turnarounds, would highly recommend! Svalbardification2026-03-19Trustindex verifies that the original source of the review is Google. Thank you for guiding me through my pre-planning and planning application for a residential self build. They also submitted my CIL exemption and provided excellent advice throughout. Money well spent. Daniel Harvey2026-01-13Trustindex verifies that the original source of the review is Google. We used Salstan for architectural drawings and building work. Elyas and team are trustworthy, efficient, friendly and understanding. One thing that didn’t go unnoticed is how they don’t charge extra for some petty things like other builders would. From the first discussion we had with Elyas he put us at ease and we really felt like he had our best interests at heart and was genuine. We wouldn’t hesitate to use his team again and wish the company the best for the future! Dan and Tracy Yee Ki Lee2025-12-22Trustindex verifies that the original source of the review is Google. I appointed Salstan Architects for my planning submission and building control application for my garage conversion project. Ibbad was the lead architect and coordinator, and he was outstanding—highly experienced in handling the full dossier, layout plans, and overall design process. His team was equally professional and knowledgeable, including a very competent structural engineer who designed the lintel for the new door opening as part of the integral garage conversion. Their layout design and structural calculation provided essential insights and clear guidance for my builder throughout the project. Most importantly, their professional advices and support guided me successfully through the building control process, resulting in final completion approval from the inspector. I highly recommend Salstan Architects for their expertise and professional services. Jen2025-12-09Trustindex verifies that the original source of the review is Google. We used Salstan for our basement conversion and they were excellent, would definitely recommend and use again. Sarah Coulson2025-12-08Trustindex verifies that the original source of the review is Google. We have just finished our project with Salstan Architecture, and we couldn’t be happier. Being a family of 6 with 4 children, we desperately needed extra living and dining space. We didn’t have experience of building, and the whole project seemed extremely daunting to us. We came across Salstan Architecture on google, initially just to help us with our design, but we immediately felt at ease and in good knowledgable hands. What we liked about Salstan, was how they were open to our ideas and listened to our wishes. We had spoken to other building companies who wanted to build their way and not the way that we would have liked. Ibbad and Elyas from Salstan listened, offered us professional advice, and we just found them so accommodating and friendly. When they informed us that not only did they offer planning, architecture and structural engineering services, but that they could also compete our project and build, we were over the moon and couldn’t wait to begin. The whole team have full comprehensive knowledge and understanding of every intricate detail and query that we ever had, and as a busy working family, we were so grateful to have Salstan building and managing our project. As with any build, we came across minor obstacles, however no matter the day or time, Salstan were in reach, and they assisted us each and every time. The communication was fantastic from start to finish, and that was really important to us. Each phase of the construction was finished on time, and we were always on track to finish at the agreed date. The tradesmen were fantastic. They were friendly, respectful, truly knowledgeable and great at their jobs. They were also great with the kids and our 3 year old was sad to see them go! All in all, I would, and have, recommended Salstan to anyone thinking of completing a building project. I am so glad to have found this company, and we couldn’t be happier with our new home. JCSCO2025-09-27Trustindex verifies that the original source of the review is Google. Excellent local firm. Used them for my lift conversion project. Had demonstrable experience in dozens of similar build project in the local area. Gave great advice on layouts and fessibility of different options. The set of drawings included 3D views from different angles allowing me to visualuze the finished project. The handled plans, calculations, and planning process. They did not quibble when it came to making small adjustments. Gave great advise on how to handle making permitted development and planning applications either together or separate to be both cost effective and increase success. In my opinion, great value for money and and great group of people to work with. Only criticism was that the building contractor side of the business were a bit slow to quote for the work that the planning side had prepared. But all in all a great experience. Anhar Ali2025-09-26Trustindex verifies that the original source of the review is Google. I was recently introduced to this company by another client of Salstan for my loft conversion project. My work is yet to start but the experience so far with Ibaad and zain has been very positive. They were very professional, honest, kept their words and got the job done on time. Ibaad replied to my queries even when he wasn’t in the country. I have already recommended my cousin to use their services and I will definitely use them again in the future. Hammad Bin Hassan2025-09-16Trustindex verifies that the original source of the review is Google. Any praise I give to MM Architecture and Ibbad would still fall short of the exceptional work they’ve done for me over the past few months. I’ve already recommended Ibbad to at least half a dozen close friends and acquaintances who are looking for a capable architect. When I first approached him, I was stuck. My building’s planning permission for change of use had been rejected once, and a second application had to be withdrawn after negative council feedback. I had already invested heavily in extensions and a loft conversion, but couldn’t achieve the ultimate goal of splitting my house into apartments. My previous architects had given up, and I was left searching for someone who could actually find a way forward. After researching extensively — comparing pricing, quality of work, and meeting different architects face-to-face — I decided to place my trust in Ibbad and his team. From the outset, Ibbad was refreshingly honest about the challenges, while also highlighting the property’s potential and assuring me he would deliver the best possible design. Unlike my previous architects, he recommended submitting a pre-application. It cost a little extra, but it proved to be the right strategy and was crucial to the ultimate success of the project. Over the following months, we worked closely to create a feasible plan for all three floors, overcoming numerous legacy hurdles and navigating my budget constraints. Ibbad not only delivered a well-thought-out design on time, but also exceeded my expectations by proposing an additional flat through meticulous planning and clever use of space — significantly increasing the property’s value. He also guided me through the council’s requirements for supporting documents, including parking surveys, BNG assessments, flood risk assessments, and landscape architecture. Every time new challenges arose, he was quick to respond, always just a message away. After months of coordination with multiple stakeholders, Ibbad’s expertise and persistence led to the successful approval of a complex planning permission. I cannot recommend him highly enough — if you’re looking for an architect, you’ll be in the safest of hands. Philip Mokuolu2025-08-07Trustindex verifies that the original source of the review is Google. Ibbad and the team at Salstan Architects have been absolutely fantastic throughout the process of designing and obtaining approvals for my HMO project. From the outset, Ibbad demonstrated a high level of professionalism, patience, and an extensive depth of technical knowledge. He didn’t just deliver what was required, he consistently went above and beyond, proactively suggesting improvements to layouts, advising on compliance issues, and taking initiative to deal with planning and other documentation efficiently. His communication was always timely and clear, and I genuinely felt like he cared about the success of the project. I’m very happy with the quality of the drawings, the support I received, and how smoothly things progressed.
