How much does a new build home cost in Bristol?

A bespoke new build home in Bristol is quoted per project, ground works, structure, services, finish and external works handled by one accountable team. Site, planning fees and architect fees are separate. We give a fixed price after the design stage.

How long does a new build take?

A typical 4-bed new build runs 9–14 months on site, plus 6–12 months of pre-construction (design, planning, discharge of conditions, technical drawings).

Can MB Design and Build act as my principal contractor?

Yes. We act as the principal contractor on bespoke new builds, managing CDM, structure, services, finish and warranty under a single accountable contract.

Why MB for a new build

Single point of contract.
Single point of risk.

Most self-builds in the South West go wrong for the same reason: too many separately-contracted parties. The architect, the engineer, the groundworker, the timber-frame supplier, the M&E contractor, each holding part of the risk and none of them holding all of it.

MB acts as principal contractor under JCT or NEC contracts, taking design responsibility from RIBA Stage 4 onwards through to building control sign-off, CIL discharge and warranty issue. You get one team, one programme, one final price.
