Straight answers before you commit.
An extension is a significant investment in your home. Before committing, discuss the proposed scope, how payments work and who will manage the build. The free site visit is an opportunity to ask questions and review the next steps.
How much does a home extension cost?+
Every extension is different, so we don't publish fixed prices. We visit your home for free, then prepare a detailed quotation with a freelance quantity surveyor. Review the proposed scope, allowances and exclusions before agreeing the work, including how any changes will be priced.
Do you handle planning permission?+
Yes, on our full turnkey package. We take your project from first concept through design and planning permission to the finished build. If you already have planning and drawings, choose build-only and we'll build from those.
How do payments work?+
A deposit secures your start date and covers site setup and initial materials. Subsequent stage payments are tied to agreed build milestones. The written agreement sets out those milestones and payment arrangements.
Will your team disappear halfway through?+
No. The team is sized to your project and stays on site until the job is done. Trades aren't pulled away to other jobs mid-build.
Is the work guaranteed?+
Yes. Every project comes with our workmanship guarantee, and we carry £10 million public liability insurance.
Which areas do you cover?+
We're based in Sturminster Newton and build across Dorset, Somerset, Hampshire and Wiltshire.
