Specification
Kitchen · Underfloor heating
Design and build inclusive: architecture, structural engineering, planning, party wall, construction, project management and LABC sign-off under one contract.
Anderson's note
Islington rarely engages on pre-application, so we went in with a well-argued application and precedent cases from the same street. The drainage modification the planners wanted was turned round in days rather than losing a planning cycle.
Anderson, founder — LCCL Construction, Finchley N3
The client's view
“Alexander and his architect and structural engineer produced the drawings for our extension and got them through planning efficiently, dealing with some drainage modifications required by the planners very quickly. They're also sorting out a party wall agreement for us on one side. Alexander has been very helpful and accommodating of our budget needs.”
