Armstrong Simmonds Architects are a RIBA (Royal Institute of British Architects) Chartered practice based in Battersea. Established in 2010, we have over 15 years of experience and specialise in residential architecture, working across the boroughs of London with specific expertise in London architects residential projects.
Our portfolio is testament to our specialist skill set in residential architects London. We pride ourselves on the highest of standards, which is demonstrated in our extensive portfolio and high levels of client satisfaction.

Aside from providing you with a beautiful design, your architect needs to navigate complex planning and building laws that regulate the construction industry. Therefore, appointing a practice with the right amount of experience is key to smooth project delivery. Although not essential, appointing a RIBA chartered practice is also an important factor to consider. Being RIBA Chartered means that the practice must adhere to a code of conduct of professionalism and ethics, ensuring quality control within the architectural industry. The experience of the practice within London is another important factor to consider, particularly as each borough has different modes of operation which can influence the design process.
Whilst the National Planning Policy Framework (NPPF) provides the backbone for planning policy, each individual borough will have its own set of policy and guidance. A particular challenge within the boroughs of London is the planning process for basement design. For such a complex undertaking, stringent planning requirements must be met in the form of traffic reports, geology surveys, and more. Another challenge is the added complexity of working with historic buildings. If your building is within a conservation area, a designated building of interest, or a listed building, any work to that building or surrounding area will be subject to strict requirements that are typically more rigorous than standard planning requirements. London residential architects and designers must ensure their clients are advised appropriately on the process and that suitable consultants are appointed to conduct the necessary work.
By law, all parties involved in any construction project must adhere to health and safety legislation. The landscape changed significantly in 2015 when new regulations were brought in under the Construction (Design and Management) CDM 2015 regulations. Similarly to health and safety, all parties involved in any construction project must work in accordance with Building Regulations Legislation. Following the Grenfell tragedy in 2017, new statutory legislation was introduced to make sure that parties involved in a construction project carry out their duties to ensure buildings are built safely and in accordance with regulations. It is essential that the practice you pick has a thorough understanding of the above legislation.

We combine creative thinking with technical expertise to guide you through every stage of your project — from concept to completion. The process typically includes the following key phases.

Simplicity and carefully considered form are at the heart of our design philosophy. We believe that a careful balance between functionality and aesthetics must be struck for your project to be successful. Rigorous process is also key in our approach and we constantly test options through various iterations – the ‘right’ approach may not be as obvious as it initially seems.
At Armstrong Simmonds Architects, we are constantly evolving and looking for new ways to explore design innovatively. We hope that our design philosophy and approach are clear from our extensive portfolio. We welcome you to get in touch to discuss your project with our residential design architects.
We are glad we found Armstrong Simmonds Architects to help us on our first project. We had bought a run-down terraced house near Clapham Common with the goal of extending and refurbing to increase value. John initially impressed us by first listening carefully to what we wanted to do, then showing us creative ways to achieve the results and finish we were looking for.
Safe to say we certainly have managed that and both John and Alan have been instrumental in doing so. The guidance and consideration at every step have exceeded our expectations and Alan’s attention to detail during the build has been critical for the high standards we have set for this project.
They have provided us with a service which reflects every stage of the design and build. Starting with the initial drawings, schedule of works, tendering and interior design. We also employed ASA for Contract Administration to be the key middle-man between us and the builder, which they were happy to help.
We are now underway with our second project with ASA and they have been able to deliver the final drawings for planning within a fairly tight time frame, without hindering on quality. I know the whole team worked hard to help bring our vision to life and it’s been brilliant working with them over the last 18 months. They have shown a great ability to solve any issues that arose quickly and are able to communicate effectively with different contractors at all levels. I have no doubt the next redevelopment project will go well.
We chose Alan and John for our extensive project and incredibly pleased with that choice and the result. We have a Victorian terraced house and wanted to do a classic loft conversion and ground floor extension. The Armstrong Simmonds team provided a vision which achieved our goals, but with a design we could have never have thought of ourselves which we love. We used them from start to finish and are incredibly glad we did. Alan supported us through the tender and renovation processes, and we are incredibly pleased with the end-product and the quality of work of builder Cezar of Vecchini. We would highly recommend Armstrong Simmonds for their vision, design thoughtfulness and exceptional assistance through the project. Thanks team!
We worked with Alan and the team from Armstrong Simmonds for 3 years from start to finish to achieve the full renovation of a London townhouse. It was a challenging brief given the nature of the property but collectively what has been achieved is an outstanding end result. Alan and John thoughtfully incorporated our vision with the realities of converting an old Victorian house and the scrupulous attention to detail, symmetry and balance achieved in the design were instrumental in us choosing Armstrong Simmonds in the first place.
In addition Alan supported us through the tender and during the renovation working with our excellent builder Cezar of Vecchini to deliver the brief. I would highly recommend if you are looking for a team to turning your vision to the end product with a very high attention to detail while still being good humoured and a generally great guy to work with. Thanks again team. Dom and Kamilla
John and his team have been brilliant to work with for our full house renovation and extension in SW London. Our house is quite unique and that combined with it being in a conservation area we knew it wouldn’t be a straight forward planning process – but Armstrong Simmonds did a fantastic job and helped us navigate us through every step. We couldn’t be happier with the detailed design and outcome.
