Specification
Victoria Plumb · Fire Doors · New Electrical Systems
Design and build inclusive: architecture, structural engineering, planning, party wall, construction, project management and LABC sign-off under one contract.
Anderson's note
Hip-to-gable plus rear dormer on a semi nearly always falls under permitted development — the neighbours are the variable. A conversation over the fence before the notice lands avoids most objections.
Anderson, founder — LCCL Construction, Finchley N3
