BUILDING IN EAST SHEEN

East Sheen features wide Edwardian streets, Victorian terraces and 1930s detached houses. These plots are ideal for double-storey side extensions, and excellent schools drive consistent family demand.

Double-storey side-return extensions fill unused alleys and add bedrooms; wrap-around extensions combine side and rear areas for large family kitchens.

Our East Sheen portfolio includes five projects: a double-storey side extension, a glass-roofed kitchen extension, a mansard conversion and two loft conversions — all within SW14.

Local advantage

Why East Sheen homeowners choose DPS for house extensions.

01 · PLANNING HANDLED

We handle the permission side in-house.

Planning drawings, building-regulations and party-wall paperwork are prepared and submitted by our own team — including for conservation-area or listed properties where extra consent is needed. One point of contact owns both the approvals and the build, so nothing falls between an architect and a separate contractor.

02 · ONE TEAM

Architects, builders, project managers — all in-house.

No subcontractor juggling. From the first sketch through structural engineering to final snagging, your project moves through people who all sit in the same office and answer to the same project manager.

03 · TRANSPARENT PRICING

From £2,500 / m² — itemised and fixed.

You pay in stages, only after each stage is signed off. Variations only happen when scope genuinely changes — and they go through written authorisation, never a verbal "while we are at it".
