Question 1

What planning permission do I need for a full-width rear extension on my SW14 Edwardian semi in East Sheen?

Accepted Answer

Richmond Borough's permitted-development rules let most Edwardian semis in SW14 build a single-storey rear extension to certain depths — up to 4 metres under standard PD or up to 8 metres under the prior-approval neighbour-consultation route. Full-width schemes that also close off the side return can fall foul of an Article 4 direction on particular streets, stripping back those rights and requiring a full planning application instead. We check the specific address before any drawings are produced, advise on the right route, handle the party-wall notices the shared boundary requires, and hand you a fully itemised quote the same day we visit.

Question 2

How much does a full-width rear extension with a new kitchen cost in East Sheen (SW14)?

Accepted Answer

Budget roughly £58,000–£105,000 for a full-width single-storey rear extension on an SW14 Edwardian semi that includes structural steels, a glazed roof lantern or bifolds, all groundworks, plastering, and a complete kitchen fit-out. The kitchen specification — cabinetry, worktops, appliances — is the biggest single variable. Projects that fold in a loft conversion or first-floor bathroom at the same time tend to save money compared with running them as two separate contracts. Every element is costed individually on the written quote, which we leave with you on the day of the site visit.

Question 3

Are hip-to-gable loft conversions standard on East Sheen (SW14) semis?

Accepted Answer

They suit the roof profile of most SW14 Edwardian semis extremely well. The sloping hip end is squared off into a vertical gable, which creates the headroom and floor area a bedroom or study needs; a rear dormer is typically added at the same time to bring in light and meet building-regulation headroom requirements throughout the new space. Both elements generally remain within Richmond Borough's permitted-development allowances for properties outside any Article 4 direction, though a structural engineer's calculations are required regardless of planning route — we coordinate that as part of the project rather than leaving it for you to organise separately.
