What it is
A way of running the job, not a type of building
Design and build is a way of running the job rather than a type of building: one firm taking on all of it, from the architectural drawings and building control to the structural work and the final build. It works for an extension, a renovation or a brand-new house.
It means one point of contact and one company answerable for the result, instead of a designer, a builder and a fitter pointing at each other when something does not line up.

Why one firm
No gap between designer and builder
When the design and the build are separate contracts, the gaps between them are yours to manage: drawings that cannot be built as drawn, prices that change once the builder sees them, and nobody clearly responsible when the two do not line up. With design and build, the firm that draws it is the firm that builds it and answers for it.
You still decide what gets built. We survey first, talk through what you want the space to do, and price the job in writing before the build starts.
Design and build or new build?
Design and build is not the same as new build
New build is what is built: a brand-new house. Design and build is how the job is run: one contract, from design through construction, for any job. A new house can be design and build, and so can an extension or a renovation.
Already have approved plans from your own architect? Then you do not need design and build: we build to your architect’s approved plans. See new build and extensions.

Questions
Questions about design and build
What is design and build?
One firm taking on the whole job, from the architectural drawings and building control to the structural work and the final build. One point of contact, one company answerable for the result.
Is design and build the same as new build?
No. New build is a type of building, a brand-new house. Design and build is a way of running the job, and it works for an extension, a renovation or a new house.
Do you handle planning permission and building control?
Yes. On a design and build job we take on the drawings and building control, and we tell you at survey whether planning permission is needed.
Can I use my own architect?
Yes. If you already have approved plans, we build to them. That is a build contract rather than design and build.
How is a design and build job priced?
After a free survey, we price it in writing and itemised, before the build starts, so you can see what each part costs.
