Design and build team managing an extension project

A turnkey service – from concept to completion

Our design and build service is built for homeowners who want a clear plan, one accountable team and a high-quality finish. We bring design, technical detailing and construction together so your project progresses smoothly from early ideas to handover.

Whether you are planning a house extension, a loft conversion or a whole-home remodel, we coordinate the details that matter: structural considerations, buildability, budgeting and timelines.

We are known locally for fixed-price quotations and transparent specifications—so you can make decisions with confidence.

What’s included in our design & build package

Everything you need to move from ideas to a finished space—without juggling multiple suppliers.

  • Measured survey and early feasibility guidance.
  • Concept design and refinement aligned to your brief and budget (see our process).
  • Planning and Building Regulations coordination where required (including planning permission support).
  • Build programme, procurement and on-site project management.
  • Handover, snagging and aftercare to protect the finish.

How we keep projects on track

We start by understanding how you want to live in the space—then we design around light, flow and practicality. Next we confirm the technical route, prepare a clear scope and agree a build programme.

During construction, you’ll have a single point of contact and regular updates. Our goal is a calm, well-managed site and a finish you’ll be proud of for years.

We work across East Molesey, West Molesey, Hampton Court, Kingston upon Thames, Esher, Surbiton, Elmbridge and surrounding Surrey & South West London.
