Anderson's note
First-time renovators need the sequence more than anything — design, party wall, planning, survey, building control, then build. Laid out at the first call, it took the fear out of the project and it ran in a few months.

The client's view
“LCCL totally refurbished our 3-bed Victorian terraced house in East Finchley and built a new 5 m side return extension. From the very first call, Alexander had a really clear process in terms of design, party wall agreements, planning, surveying, building control and the build itself. It gave me great confidence going into this for the first time. The process took only a few months, which is impressive, and everything is to spec. The LCCL team, their electricians and plumbers have been great.”
