About us


Design quality is at the heart of our ethos whether it be in realising a modern contemporary project or conserving a listed Victorian Villa. We enjoy working with architects and clients helping them realise their vision through the use of creative and efficient engineering solutions. We always design with simplicity of construction in mind providing practical details to builders.




We undertake the design of new builds, extension works and alterations to existing properties. We specialise in the assessment and diagnosis of defects to buildings providing a full structural surveying service. We have extensive experience in the diagnosis of defects to masonry, steelwork, concrete and timber structures.




The Engineering team at DHD Structures have experienced the full range of structural engineering  projects from the removal of load bearing walls in domestic properties to the £100m+ redevelopment of the Bristol Royal Infirmary. Each project regardless of its size is addressed with the same care and dedication to ensure our service meets the clients requirements.


"Duncan is a brilliant engineer. He is incredibly knowledgeable, thorough and understands the complexities and challenges of delivery high quality design. I’ve worked with Duncan for about 15 years and find him friendly, quick to respond and adaptable when issues arise. If you are looking for an engineer that is as comfortable delivering small one-off commissions as he is with multi-million pound commercial developments then Duncan is your man."
