Extensions
Home extensions designed and built to extend your living space without the disruption of moving — rear extensions, side returns, double-storey, and wrap-arounds across London and Hertfordshire.
About this service
Adding space is one of the most effective ways to improve your home, and KV Design & Build Ltd manages the entire process under one roof. We assess what is achievable within permitted development or full planning, produce the design and structural calculations, handle any necessary applications, and then build to the highest standard. Rear single-storey kitchen-dining extensions, side-return infills that reclaim wasted space in London terraces, double-storey side extensions on Hertfordshire semis, or wrap-around combinations — we work across all types. Our North London teams understand party-wall procedures and the constraints of conservation areas; our Herts teams are experienced with the larger plots typical of the commuter belt.
