D3 Architects

We have been dealing with Simon at D3 Architects. We feel a strong sense of confidence in his practical understanding of the issues surrounding our proposed development. He is well informed and his advice has been essential in avoiding pitfalls. Simon and D3 offer much more than expert architectural and design services. Simon has negotiated the planning application process for us and enabled us to work around whatever obstacles the planners put in our way. We have ended up with a plan that we are sure will work. Simon's knowledge of associated professionals in areas such as ecological and other survey work, building and drainage has also been useful in making the project viable. I would thoroughly recommend Simon and D3 to anyone else.

We used Simon Longworth-Riggs from D3 during the Winter - Spring 2021 for some complicated works to our newly purchased cottage in Mylor, Cornwall. The challenges were the design of bringing two houses back into its original one, which ultimately was reducing the size of the building and not extending…and trying to plan this with a builder in the middle of COVID lockdown when we were not allowed to come down and meet anyone in person. Simon was nothing short of professional and helpful , he would listen to ideas, talk through them and convert all into a credible plan of action, which was ultimately presented to the Planning Department. We were very impressed with his final draft application because it told the story of what we were trying to achieve and how this would align with the expectations of living in a conservation area. Our initial application was successful and we are nearing the end of this project build. So would we recommend Simon - Of course we would Was it value for money - It was a reasonable price and Simon made the effort in places to reduce his costs to us For any further details please do not hesitate to contact us Sally & Adrian Davis Mylor, Cornwall

We first approached D3 when we were house hunting to get some advice on adapting a property to our own needs including an indication of the approximate budget. As potential buyers Simon provided very sound advice which helped in our deliberations. We later engaged Simon on a major re-design of our 1960’s bungalow involving significant demolition and rebuild. Simon worked on the design with us bringing alive multiple iterations of the plan, providing detailed drawings and high level costings. Simon listened to what we wanted for the house and translated that into detailed plans. He managed the planning process and building regulations efficiently and successfully. Since we were based 200 miles away, much of the work with us had to be done remotely - Simon handled this well and was easy to work with. Whilst we selected the builder ourselves, Simon was very helpful in suggesting local contacts and contractors for various elements of the project. Simon kept in touch throughout the build which took nearly a year, completing the job at the end by providing as-built drawings. We found him thoughtful, thorough and responsive and would recommend his services to anyone contemplating a building project in Cornwall. We’re absolutely thrilled with our wonderful new house!

Simon from D3 Architects has supported us through our two-story extension planning, and has been able to source tenders from several builders during a challenging post-COVID time where reliable builders have been scarce. Simon has kept in touch with us throughout and has been on hand to answer questions or concerns we had with our project, including additional home visits when requested. I would recommend D3 services and would use them again in the future.

We cannot overstate quite how happy we are with the outcome of our engagement with D3. From the very first meeting with Simon we were impressed and reassured in equal measure. Simon listened carefully to our proposed ideas and within a few days presented us with a couple of options for our planned extension, as well as (having asked permission) producing an additional drawing that was nothing like our original idea, but which encapsulated perfectly the essence of what we wanted but in a way which we had not even considered possible. This plan not only demonstrated Simon's brilliant architectural skill but also showed quite how well he had understood what we wanted to achieve from the space. The result was a much more adventurous (for us) renovation which will revolutionise how we use the space in our home. The building work has now commenced and Simon has been in touch regularly to ensure things are going ok, with support and assistance offered for whenever it may be required. We really couldn't ask for more and are very grateful to Simon for his involvement.

Despite the current restrictions on movement, Simon has provided a first class service in a timely manner and with professionalism.

Simon helped us design our new garden room when we had no idea what we were doing! Helped us through the process which helped us see what we wanted! Always friendly and polite, recommended

My project was a refurbishment and extension to a 1950s bungalow to create a large living area with 4 bedroom 3 of which are on en-suit and to create an expansive living/dining area with sliding doors onto a large patio taking advantage of the valley and river views. Simon Longworth-Riggs was the architect that drew up the very detailed plans for the work, he ensured necessary engineering calculations were carried out and all the paperwork to obtain planning permission was completed. He provided site visits to check work and any concerns raised ensuring the build went smoothly. Simon was easy to work with he was pleasant in his manner, a good listener and always helpful with ideas you wanted to discuss. The project took approximately one year to complete.

Professional drawings supplied and BRegs was no problem. Any on site problems or queries always answered concisely and promptly. Ours was a very small project but this made no difference to the service provided by Simon.

We found Simon at D3 very easy to work with and he always completed the work required promptly. He was happy to listen to our ideas but his professional input was invaluable and he was very flexible when the remit changed mid project. Would highly recommend to anyone

It was a huge relief to work with Simon at D3! We had a number of planning and listed building conditions to discharge before we could commence our build and he successfully negotiated all of them with the planners. We're delighted, thank you!

I strongly recommend D3 Architects based on the service they gave us with the design and build of a substantial garden room at our property near Truro. At our initial meeting, Simon was professional, enthusiastic and imaginative. He took responsibility for the architectural design of the building, planning issues, sourcing and managing a structural engineer to check steelwork, sourcing and managing a building contractor and glass window / door supplier. We were happy throughout the project with Simon's approach, communication and reliability. His dealings on our behalf with the other parties involved in the design / build were smooth and efficient. Importantly, we are delighted with the final building and would have no hesitation to use D3 again when the need arises.

Simon and D3 were superb from the start. The most important point, was taking the time to understand what we wanted from our project, how we really wanted to live, and how to maximise the space. Next came the ability to take all the worry and challenges away from us. Dealing with tricky neighbours objections, helping planning and building regs see sense, and most of all enabling us to get on with the important job of imagining how it would be when completed. A few years on, and we are just as delighted with the outcome and design as we were when it was first completed. D3 most certainly lived up to their motto of Design, Delight, Deliver.
