Why Putney is one of the best places in London for a loft conversion
Putney has two distinct kinds of loft-friendly housing. The grids of Victorian and Edwardian terraces off the Upper and Lower Richmond Roads have the rear outriggers and mid-pitch roof slopes that suit rear dormers and L-shaped dormers. Then, heading up the hill towards Roehampton, the 1930s semis have hipped roofs that lose usable space at the sides, which is exactly what a hip-to-gable conversion fixes.
Planning is refreshingly simple in SW15: the whole of Putney sits under Wandsworth Council, so there are no boundary complications. Most rear dormers and hip-to-gables proceed under permitted development with a Lawful Development Certificate, usually decided in around 6 weeks; full applications typically take 8 to 10 weeks. The main exception is the riverside, where the Putney Embankment conservation area restricts river-facing roof alterations and a low-impact Velux conversion is often the smarter route.
Putney is directly across the bridge from our Fulham base, a few minutes by road, which makes it the fastest survey response of any area we cover. Our project managers cross Putney Bridge most working days, so mid-build questions get answered in person, not over the phone. A good share of our SW15 work now comes from neighbours who watched a build happen two doors down.

Our projects in and around Putney
Which loft conversion suits a Putney home?
Putney's housing splits cleanly by street: terraces near the river and the Upper Richmond Road, semis up the hill. Here's what works where.
Rear DormerWhy it suits Putney
The workhorse for the Victorian and Edwardian terraces off the Upper and Lower Richmond Roads. Usually permitted development, with a finished cost typically £56k–£70k for a master bedroom and en-suite, and the fastest route to a fourth bedroom in SW15.
£56,000 – £70,000
Read more about rear dormersL-Shaped DormerWhy it suits Putney
Most of the terraced streets between the two Richmond Roads have a rear outrigger, which is exactly the footprint an L-shaped dormer builds over. Adds two rooms in one project, usually a master bedroom plus a generous bathroom or study, and typically stays within permitted development.
£66,000 – £82,000
Read more about l-shaped dormersHip-to-GableWhy it suits Putney
The right answer for the 1930s semis on the streets running up towards Roehampton and Putney Heath. Rebuilding the hipped side roof as a vertical gable, usually paired with a rear dormer, converts a loft that's otherwise too tight at the edges into a full storey.
£58,000 – £72,000

- Any conversion of a flat or maisonette
- Properties within the Putney Embankment Conservation Area

Conservation areas affecting Putney
- Putney Embankment Conservation Area — Covers the riverside around the Embankment, the boathouses and the streets running down to the Thames off the Lower Richmond Road. River-facing dormers are typically restricted; Velux conversions or carefully designed rear alterations are usually the route.
- West Putney conservation pockets — Parts of the larger Edwardian avenues on the West Putney hill carry conservation considerations. We check your street against Wandsworth's conservation maps before the survey.
- Roehampton Village Conservation Area — At the western edge of SW15, Roehampton Village has tighter controls on roof alterations. Loft conversions are still achievable but usually need a full application.

What does a loft conversion in Putney cost?

We were nervous about committing to such a big project, but the team made it the smoothest experience. They stayed on budget, finished a week early and even sorted the snags before we'd noticed them. Our bedroom is the best room in the house now.
Sarah & Tom
L-shaped dormer · Clapham
From the first survey to handover, everything happened when they said it would. The fixed price genuinely was fixed, and the weekly photo updates meant we always knew exactly where the build was. The dormer has completely changed how we use the house.
James R.
Rear dormer · Wandsworth
Our loft was a dumping ground for ten years and now it's the nicest room we own. The crew were tidy, polite and honest about what was possible, and the finish is better than we dared hope for.

Loft conversion questions from Putney homeowners
How much does a loft conversion in Putney cost?
Loft conversions in Putney typically cost £40,000 to £100,000 depending on the type and the property. A standard rear dormer on a Victorian terrace usually falls between £56,000 and £70,000. L-shaped dormers over a rear outrigger run £66,000 to £82,000, and a hip-to-gable on a 1930s semi towards Roehampton is £58,000 to £72,000. Velux conversions start at around £40,000 and mansards run up to £100,000. Every figure is VAT included and confirmed in writing after a free home survey.
Do I need planning permission for a loft conversion in Putney?
Usually not. Rear dormers, L-shaped dormers and hip-to-gable conversions on Putney houses generally fall under permitted development, needing only a Lawful Development Certificate. You will need planning permission for a mansard, for any conversion of a flat or maisonette, and for most work within the Putney Embankment Conservation Area or facing the river. We confirm your street's exact position at the free survey and handle whichever route applies.
How long does Wandsworth Council take to approve a loft conversion?
A full planning application typically takes 8 to 10 weeks with Wandsworth Council. A Lawful Development Certificate, which is all most Putney dormer and hip-to-gable conversions need, is usually decided in around 6 weeks. All of Putney sits under one council, which keeps things simple. We prepare and submit everything and build the approval time into your project programme.
What's the best loft conversion for a 1930s semi near Roehampton?
A hip-to-gable, almost always. The 1930s semis on the streets running up towards Roehampton and Putney Heath have hipped roofs that slope in at the side, leaving too little headroom for a dormer alone. Rebuilding the hip as a vertical gable, usually paired with a rear dormer, creates a full-width storey with space for a double bedroom and shower room, typically £58,000 to £72,000.
Can I convert my loft in the Putney Embankment conservation area?
Usually, yes, but the type changes. River-facing dormers are typically restricted near the Embankment, so a low-impact Velux conversion, or a rear dormer approved through a full planning application with a heritage statement, is normally the route. We have delivered both in SW15 and prepare all the conservation paperwork as part of the fixed quote.
How quickly can you survey a house in Putney?
Faster than anywhere else we work. Putney is directly across the bridge from our Fulham base, a few minutes by road, so we can usually offer a survey slot within 1 to 2 working days of your enquiry, sometimes same-day. It also means your project manager is passing through SW15 most working days once the build starts.
