About Design and Build
We are Design and Build, an architect-led design and build company in London. We take the ideas in your head, put them down on paper and then turn them into bricks and mortar – on time and on budget.
Everything you need is under one roof: our own architects, structural engineers, party wall surveyors, interior designers and skilled tradesmen. You never have to find, brief and coordinate separate professionals – we work with you from the very first site visit to the finishing touches.
From house extensions, loft conversions and full renovations to commercial fit-outs, we offer a complete turnkey service: design, planning permission, Building Control approval, construction and interiors, all managed by one dedicated team.

Everything under one roof
Architects
Concept, drawings, planning applications and building regulations – handled in-house so your design and your permissions move together.
Structural engineers
Calculations and structural design for extensions, loft conversions and load-bearing alterations, coordinated with the architect from day one.
Party wall surveyors
Notices, awards and neighbour agreements taken care of before work starts, so your project is never held up at the boundary.
