design and Build

At Bloom Builders, we deliver design and build construction projects across London, providing a coordinated approach from early feasibility and design development through to construction completion. This approach reduces risk, improves cost certainty and shortens overall project programme.

Where required, we work alongside Malone + Pike Architects or collaborate with client appointed architects and consultants. Both companies operate independently but regularly coordinate to provide a joined up design and construction process where clients want a single coordinated delivery team.

What Is Design and Build?

Design and build is a project delivery model where design development and construction are coordinated through one lead contractor team. This helps reduce communication gaps between design and construction and allows cost and buildability decisions to be tested earlier in the design process.

Design and build is particularly effective for complex structural projects, refurbishments and extensions where early construction input improves overall project outcomes.
