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 period apartment the services are the job: rewiring for a smart system, new plumbing runs and the licence to alter all have to be agreed with the freeholder before a single wall comes down. We settle that at the design stage so the sixteen weeks on site hold.
