Please describe a recently completed project or tell us about the bespoke service that you offer

"High-end property refurbishment in a Listed building in the heart of Hampstead: We provided our overseas client with reassuring honesty as we carefully navigated the complex nature of a dated and perishing interior. It was an amalgamation of two flats and a complete back to bricks renovation that saw the first-floor of ‘Bay Tree Lodge’ converted into one high-end luxury apartment."
