What areas do you cover?

We're based in East Molesey (KT8) and typically cover Elmbridge, Surrey and SW London within roughly a 20-mile radius—including Kingston upon Thames, Esher, Hampton Court, Thames Ditton, Weybridge and surrounding areas.

What information should I include in my enquiry?

If you can, share your postcode, the type of project (extension, loft conversion, renovation or design & build), a rough budget range, ideal timeframe and any links/photos that show what you're aiming for.

Do you offer site visits and quotations?

Yes. Once we understand your goals, we can arrange a visit to discuss feasibility, constraints and next steps. Where appropriate, we provide a clear, fixed-price quotation with defined scope and specifications.

Can you help with planning permission and Building Regulations?

Yes. We can advise on whether planning may be required and support applications if needed. We also coordinate Building Regulations compliance and inspections as part of a well-managed project. Learn more: Planning Permission and Building Regulations .

Do you manage the full design & build process?

We can take care of the full journey—from early ideas and design coordination through to construction, finishes and handover—so you have a single point of accountability. See: Design & Build and Our Process .
