Design and build inclusive: architecture, structural engineering, planning, party wall, construction, project management and LABC sign-off under one contract.
Anderson's note
Two storeys on a semi means the first-floor wall sits right on the party line — we start the party wall process at the first meeting, because it can add three months if it starts after the design is finished.
