    Extensions

    A good extension should feel like it was always part of the house. That comes down to getting the proportions, the rooflines, and the materials right, not just adding square footage. We manage the full process, from drawings and approvals through to the finished, decorated space, working with trusted local trades throughout so you have one point of contact.

    How It Works

    1

    Consultation & Feasibility

    We look at what you want to gain, how it connects to the existing layout, and any planning or access constraints before anything is drawn up.

    2

    Drawings & Approvals

    We coordinate the architectural drawings, structural calculations, building regulations, and any party-wall agreements needed.

    3

    Groundworks & Structure

    Foundations, drainage, walls, and roof structure, built to the drawings and inspected at the right stages.

    4

    Fit-Out & Finish

    First and second fix, plastering, decoration, and the connection back into the existing house, then snagging and handover.

    What Does It Cost?

    Cost depends on size, number of storeys, ground conditions, and how much of the existing house is affected. We'll walk the site and put together a detailed, itemised quote.

    Extensions is available across Cornwall, from our base in St Austell to Truro, Falmouth, Newquay and beyond. See all areas we cover.
