Fees shown are for design, drawings and planning. Construction is quoted separately through our design & build service — try the interactive visual builder for an indicative build cost. Final fees depend on the size and complexity of your project and your site.

Our flagship · design & build

We design it — then we build it.

£1,600–£2,000 / m²
per square metre of new floor space · + VAT

The complete service. We design your project, secure the permissions and engineer the structure — then build it as your main contractor for a fixed price agreed before work starts.

One team, one point of contact, one accountable result, from the first sketch to the final coat of paint. Pricing is based on the floor area of new space we create, so it scales fairly with the size of your project; the premium rate reflects higher specifications and finishes.

Already have a design from another architect? We're happy to build an approved scheme as your main contractor.
