Design and build inclusive: architecture, structural engineering, planning, party wall, construction, project management and LABC sign-off under one contract.
Anderson's note
In a conservation area the extension is judged on how well it disappears into the house. We matched the brick, the bond and the window proportions to the original, and the officer signed it off without a single amendment.
