Design it in 3D

Extend your home. Or build new.

Add an extension to a family home, or shape a bespoke new build from 2,500 to 10,000 sq ft. Turn it around, switch it to dusk, then send it to us.

Simple. Book a free consultation and one of our experienced designers will visit your home to discuss your vision. We then provide a detailed consultation report, a fixed-price quotation and a works schedule.

No. The initial consultation and quotation are completely free, with no obligation.

We only accept a select number of projects each year to keep our standards high. If you're planning a project, get in touch early to secure your spot.

It depends on the size, location and type of extension. Many projects fall under permitted development, but conservation areas, listed buildings and larger extensions need an application. We assess it at your consultation and guide you through Surrey's planning process.

If your extension is built on or near a boundary shared with a neighbour, you may need a party wall agreement. It's a legal requirement to inform neighbours and agree on the work. We'll advise if it applies and recommend trusted party wall surveyors.

Let's talk about your home.

Free consultation, fixed-price quote and one team from the first drawing to the final handover.
