One Team. Every Stage.
KV Design & Build Ltd is a building contractor covering London and Hertfordshire. We manage residential and commercial projects from planning through construction and fit-out — under a single contract with a single team.
That means no gaps between your architect and your builder, no blame-shifting when things need resolving, and no need to manage multiple contractors yourself. You deal with us, and we deliver.
From a kitchen refurbishment in a North London Victorian terrace to a bathroom renovation on a Hertfordshire semi, from a full-property refurbishment in Camden to a new-build residential property — we bring the same rigour, the same standards, and the same integrated approach to every project.
