How design and build works

Anderson's note

Kensington & Chelsea will look at every elevation, so the wraparound was drawn to read as two modest additions rather than one big one. Completed on time with the family living in for most of it.

Anderson, founder — LCCL Construction, Finchley N3

The client's view

“Very happy with the quality of the design and build on our project. The build was completed on time and disruption minimised.”
