Side Return Extension Specialists in Putney (SW15)
Professional side return extension specialists in Putney, South West London.
Why Choose All Well for Side Return Extensions in Putney?
Most Victorian and Edwardian terraces in SW15 have a narrow side passage running down the flank of the house. A side return fills that gap, opens the kitchen wall with a structural steel beam, and adds 8–15 square metres to the ground floor without losing garden. The wider Edwardian semis around Putney Hill allow a more ambitious infill than the tighter Victorian terraces of neighbouring Battersea.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Side Return Extensions Tip for Putney Homeowners
Wandsworth Council runs one of the faster permitted development processes in South London. If your SW15 property sits within the Putney Embankment, Oxford Road, or Wandsworth Park conservation areas, glazing and roof finish need to match the existing character, but rear extensions usually still avoid a full planning application. A Lawful Development Certificate (£129) gives you Wandsworth's written confirmation before groundwork starts.
Side return extensions on Putney SW15 terraces
A standard side return infill covers structural steelwork, foundations, glazed roof, electrics, plumbing, insulation, plastering, and decoration. Fixed price confirmed after a free site visit, with foundation depth set by a trial hole first.
Ground conditions: Putney Heath vs lower SW15
Near Putney Heath, river terrace gravel allows foundations of around 1.0 metre. Closer to the Thames, London Clay and higher groundwater push that to 1.2–1.5 metres, which means deeper digging and more concrete. We confirm depth before issuing the contract.
Wraparound on Putney's Edwardian plots
Side return plus rear extension gives you the largest open-plan ground floor. Putney's wider Edwardian semis around Putney Hill suit a 4–5 metre rear addition that still leaves usable garden.
Permitted development for SW15 side returns under Wandsworth rules
Most Putney side returns proceed under permitted development: no planning application, no committee. Stay within 3 metres of the original rear wall, below 4 metres at the eaves, and cover no more than half the garden. We apply for a Lawful Development Certificate (£129) if you want Wandsworth's written confirmation before groundwork starts.
Conservation areas: Putney Embankment and Oxford Road
The Putney Embankment, Oxford Road, and Wandsworth Park conservation areas require glazing and roof materials to match the existing character. Rear extensions are generally accepted, with restrictions mainly hitting street-facing changes. We confirm conservation area status at the site visit.
Flood risk for lower-lying SW15 addresses
Within 200–300 metres of the Thames or near Wandsworth Park, properties may need a Flood Risk Assessment as part of any planning submission. We check the Environment Agency maps at the survey.
Build process and timeline: side return on a SW15 terrace
Ten to fourteen weeks from start on site to Building Control sign-off. Foundations weeks one and two, structural steelwork and masonry through week six, then roofing, glazing, first and second fix trades. Sign-off and FENSA-registered glazing are included in the contract.
Glazing choice for a Putney Victorian side return
Flat glass roof is the most common choice: straightforward to detail against the party wall, good daylight. Crittall-style steel frames suit SW15's period stock. On south-facing returns we discuss solar-control glass at the design stage.

Frequently Asked Questions
- How much does a side return extension cost in Putney?
- Every SW15 side return is priced after a free site visit, because the work covers steelwork, foundations, glazed roof, electrics, plumbing, insulation, plastering, and decoration. Foundation depth varies across SW15 and is confirmed by a trial hole before the fixed-price contract is signed, so the figure we give you is the figure you pay.
- Do I need planning permission for a side return extension in Putney?
- Most SW15 side returns fall under permitted development: 3-metre rear projection for terraces, 4-metre eaves height, no more than half the garden covered. Conservation areas in Putney (Putney Embankment, Oxford Road, Wandsworth Park) add glazing and materials requirements, but rear extensions usually still avoid a full application. Lawful Development Certificate is £129, and we apply as standard.
- How long does a side return take in Putney?
- Ten to fourteen weeks from start on site to Building Control sign-off. Starting March to October reduces the risk of winter groundwork delays, which matter more on lower-lying SW15 plots near the Thames.
