Welcome to D3 Architects, Truro, Cornwall. We believe that everyone should experience great architecture, and that it should be available to both domestic and commercial clients. Established in 2009 with the motto, Design, Delight, Deliver; that is what we do. Our experience in a wide range of commercial and residential project types, from new houses to doctors' surgeries to factory extensions to design and build, often wins us work as contractors and other professionals recommend us due to our thorough drawings and approachable nature.
Our Philosophy
As architects, we believe that every client, project, and site is unique, requiring a unique bespoke solution. We are here to help and assist our clients in achieving their dreams. Success requires teamwork and the right team. Sustainability is an essential ingredient to any project - not a bolt-on. Great design makes for great buildings that are enjoyable to use and inhabit.
Our Services
From a feasibility study to help writing a brief, we can take you right from the start to putting the keys to your completed project in your hands. After a free initial consultation and successful appointment, we will proceed to produce sketch schemes for client approval and comment. Only when we have a scheme that you are completely happy with do we proceed to making a planning application. Once successful, we proceed to produce construction drawings for building regulation approval. This also enables our clients to contact contractors and get accurate quotes for the work. We can assist you with tendering your project. Once works start on site, we can monitor the contract, make periodic visual inspections, or just be on the end of the phone to help when needed. We are here for clients to help them as much as they need.
Residential Architects
Whether you need a loft conversion, extension, and remodel or a new house; we can help make it a reality. Following our free initial consultation, we will visit you to discuss your needs and how we can best help you. We have experience in working to both Passivhaus and the Code for Sustainable Homes standards, and we can deliver the design that meets your energy needs. We can even recommend natural insulation materials and finishes to help make your completed project a healthier one.
Commercial Architects
From developing masterplans to extensions, we can show you how to maximise your budget and sustainability credentials. We take great care to ensure that our clients are looked after and given the help they need when they need it. We are here to help you for as long as you need us. To further assist our self-build clients, we are members of the National Self-Build Association (NaSBA), which enables us to give you greater support.
