Specification
Lusso stone · LPD Doors
Design and build inclusive: architecture, structural engineering, planning, party wall, construction, project management and LABC sign-off under one contract.
Anderson's note
Six weeks on site is realistic for a rear dormer when the steel and the staircase are designed before the scaffold goes up. The Juliet balcony is the cheapest way to get the garden view without a terrace application.
Anderson, founder — LCCL Construction, Finchley N3

“Great work ethic, with attention to detail and value for money. Was helpful from start hence why we choose them for works. Went from very dated old house to brand new house in few months. Alexander made sure all is as it should and we couldn't be more grateful.”
