A detached house in Hadley Wood with good bones but a layout that no longer suited a growing family. The sections that could not be upgraded cost-effectively were demolished and rebuilt to a new standard, keeping the structure worth preserving. The result is a contemporary open-plan family home with a cinema room, a gym in the outbuilding, a sun-lounge terrace with glass balustrades and a landscaped garden with a football pitch — 12 months on site, one design and build contract.

Anderson's note
Knowing what to keep is the skill on a job like this. We kept the structural elements that were sound and rebuilt everything that could not be brought up to a modern standard economically — that is why it came in as a rebuild and not a full new build price.
Anderson, founder — LCCL Construction, Finchley N3
The client's view
“I am very happy with the results of my newly built home completed by LCCL Construction. This was a big project and a huge decision for us — to go from the initial idea to completing the full build took much planning and consideration. Team LCCL have been so fantastic, by our side throughout, helping us with every decision, keeping us motivated and on track and staying laser focused on all the necessary details. This has enabled us to achieve our dream home which we will enjoy for years to come.”
