    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.

    John and team did a great job designing and drawing up plans for our extension, loft conversion and layout redesign. Very responsive to our frequent changes of mind and easy to deal with. The builder was very complimentary about the detailed drawings, making things straightforward for them.

    John and Nick from Armstrong Simmonds did a great job stretching some plans we brought them and helping us navigate the tricky planning process to deliver our best project yet. They were extremely user friendly, reliable and efficient.

    Johns integrity when we realised we’d initially selected the wrong builder really stood out and enabled us to partner up with an exceptional builder who we would highly recommend to anyone else. Overall we had a great experience and would highly recommend Armstrong Simmonds again.

    I cannot recommend Armstrong and Simmonds architects highly enough. Within minutes of John meeting us at our home he had understood our brief and was sharing a vision that ticked all of our boxes.

    We had met with other architects who did not inspire us and told us the shape we wanted for our extension would not be possible. John had excellent knowledge of the local planning rules, researched planning submissions in the immediate area and was confident that he would get our application through – and he did!

    During the detailed design process John and his team listened closely to how we wanted to use the space. He came up with many design features and solutions to save costs and keep our dream design within our budget.

    Throughout the process they delivered an innovative plan that felt personal to us in a professional and timely manner.

    We found John and his team to be responsive, helpful and caring. They went above and beyond to get our project over the line and I have no hesitation in recommending the firm to anyone looking at home extension/improvement. We would not look anywhere else for any future builds!

    We appointed Armstrong Simmonds Architects following a competitive tender to remodel and extend a Victorian terraced house in Southfields. We worked closely with John Armstrong on the initial designs and the planning considerations. Surveying of the existing property was swiftly conducted and the team were very proactive in the management of our planning applications which were granted with no amendments. Although we only specified a basic drawings package our builders and those that tendered for the project were complimentary on the detail and thoroughness of the plans. John also made himself available to discuss issues during the build which has been extremely helpful.

    I would recommend asking to see practical examples of what is included at each price point to ensure expectations are clear on what is included.

    In addition we have appointed Armstrong Simmonds Architects to produce drawings and manage the planning application for garden gym building and will likely work on additional projects with John and the team.

    As a small developer I felt that Armstrong Simmonds filled the brief extremely well. I appointed Armstrong Simmonds in 2012 after vetting several other similar architectural firms. What struck me at the time was the range of expertise within the firm, but also their ability to negotiate the often difficult passage of the planning process, but also some very useful contacts to the table. They have worked on several plans for me and are capable of bringing to fruition not only the plans, but also careful attention to details, architectural features, along with much needed sage advice. Their costings are reasonable and transparent. They are always ready to communicate both over the phone and in person and if the architect that you want to speak to is unavailable, they do call you back the following day. I cannot recommend them enough.

    Having worked with Armstrong Simmonds Architects on various residential projects I can highly recommend them. Their team understands the client’s needs and ensures that the project runs smoothly. It is extremely beneficial working with technically competent architect that leads the desgin process and delivers well thought final product

    Armstrong Simmonds Architects fully understood our brief when we were redesigning our property. They quickly understood what we were looking for and fully met the brief. We were delighted with the result and can’t recommend them highly enough for their professionalism, creativity and attention to detail.

    Martin Drummond

    John and Nick did a fantastic job firstly in drafting the plans for our basement conversion and side return, then also in helping us obtain planning permission within the restraints of a conservation area. Nick was very pleasant to deal with, very proactive and responsive, and went the extra mile to get the critical aspects of the design through planning.

    We received excellent advice when refurbishing a four bed house, including carrying out a wrap around extension to the kitchen area, proposing some very attractive and clear ideas. As a company they were very good with communication throughout the whole planning and building process.
    Overall, very happy and wouldn’t hesitate to recommend them to anyone

    We had a fantastic experience with John and the team at Armstrong Simmonds. We have a beautiful home and would happily use them for our next project…. hopefully even bigger next time! Flawless from beginning to end, I thoroughly recommend them.

    Linda Roberts

    Architects Armstrong Simmonds were appointed by us to turn our concept of open plan living into reality, which they did with extraordinary vision and design flair. The AS team listened carefully to our ideas and transformed an ordinary detached house into a breathtakingly beautiful home that offered light, space and a lifestyle that exactly reflected our needs and requirements . AS worked closely with us and our builder, and their focus to detail in the design and build was impressive. This young architectural practice in our opinion, offers something more. They listen, understand and are unique in their ability to conceptualise, plan and build with imagination, whilst considering aesthetics and functionality.

    Most of our projects deliver bespoke architectural features which have been carefully designed to fit uniquely into your home. These items typically include bespoke glazing, joinery, staircases, lighting, landscaping and much more. We put particular emphasis on glazing; at Armstrong Simmonds Architects, the design expertise of our architect studio allows us to identify how best to incorporate glazing elements into your project to transform what are often dark existing properties. Maximising the presence of sunlight can help to keep your home warm and in turn minimise your energy consumption. These glazing elements are designed in collaboration with glazing specialists to suit design needs.

This process is not only about getting approval for your planning submission, but also making sure we work together to achieve your vision. We do this by working with you to understand your design sensibilities from the outset, then we take you along the concept development journey; sharing updates about the design brought to life using 3D imagery. If you do not have a particular vision in mind, our team can assist you with that during the briefing process. We can provide interior design services or collaborate with an interior designer to achieve the outcomes you desire. This sets the stage for transforming your dream home into reality.
