Side return extension in Roehampton
For homes in Roehampton, a side return extension is often the simplest way to gain space without moving. Infilling the narrow passage beside a Victorian or Edwardian back addition. We take it from survey to completion certificate.
We cover Roehampton (SW13, SW14 and SW15) as part of our Greater London work. Side returns suit the Victorian and Edwardian terraces found across parts of Greater London, where the kitchen sits in a narrow back addition.

How much does a side return extension cost in Roehampton?
A side return extension in Roehampton is priced at £2,990–£4,940 per square metre including VAT as a guide, before kitchen fit-out and fees. London prices sit at the top of our range because of labour rates, access through the house, parking suspensions and skip licences.

| 2 m wide × 6 m deep (12 m²) | £36,000–£59,500 |
| 2.5 m wide × 7 m deep (17.5 m²) | £52,500–£86,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a side return extension in Roehampton?
Whether your side return extension in Roehampton needs a planning application depends on its size, your house and any local restrictions.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Roehampton like to extend?
Period terraces in Roehampton sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension. In Roehampton we check the boundary line and the neighbour's gutter before drawing a side return, because a few centimetres decide whether the wall goes on or beside the boundary.

Where does the drainage go?
Side passages often carry the soil and rainwater pipes. We survey them first and reroute them under the new floor where needed.

Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do you handle building control in Roehampton?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
