Design-led residential architecture, with real knowledge of the Brentwood area.

Studio 40 is a RIBA Chartered architecture practice based in nearby Billericay. We combine architecture, interiors and project management, working with homeowners across Brentwood and the surrounding villages who want a genuinely considered approach. Not just a planning application.

Working in Brentwood means understanding the planning landscape here properly. The borough has a well-established Local Plan introduced in March 2022, a significant number of Conservation Areas in the villages surrounding the town, and a substantial Metropolitan Green Belt covering much of the borough. Unlocking potential within the Green Belt requires careful thinking, clear strategy, and an architect who knows when and how to make the case.

We are honest from the first conversation about what is achievable, what the planning picture looks like, and what it will cost. If you are thinking about extending, refurbishing or rebuilding your home in Brentwood, Ingatestone, Doddinghurst, Mountnessing or the surrounding area, we would like to hear about it.

Our minimum construction value is £200,000. Full details of our fees and how we work are on our Costs page.
