Loft conversion cost
in Putney.
Putney — across Putney Bridge from Fulham — has been one of 2VP's busiest loft territories since 2018. The Edwardian and inter-war terraces between Upper Richmond Road and the heath are textbook L-shape dormer candidates.
What makes loft work in Putney distinct.
Housing: Edwardian three-storey terraces with kitchen outriggers, plus inter-war semi-detached houses on the south side towards Putney Heath.
Planning: Putney Embankment, West Putney and Lower Common conservation areas restrict PD on the river-side streets, but most of central Putney qualifies for PD on rear dormers.
Applications go to LB Wandsworth. We submit on your behalf and handle conservation officer correspondence end-to-end.

What Putney homeowners ask us.
Do I need planning permission for a loft in Putney?
Putney Embankment, West Putney and Lower Common conservation areas restrict PD on the river-side streets, but most of central Putney qualifies for PD on rear dormers. Outside conservation areas, most rear-dormer conversions in Putney qualify for permitted development (PD) within the 40m³ (terrace) or 50m³ (semi/detached) volume limits. Mansards always need full planning. We check your specific address before quoting and submit the application on your behalf.
Are Putney loft conversions usually PD or full planning?
Outside the conservation areas — Putney is one of the easier London markets for PD. Standard rear dormers within the 40m³ volume limit and matching tile/slate get a Lawful Development Certificate in about 8 weeks from Wandsworth Council. Conservation-area properties (around the embankment and lower common) need full planning.
How long does a Putney loft conversion take?
Typical timeline: 6–10 weeks for design and planning (longer in conservation areas like much of Putney), then 8–14 weeks on site for a standard dormer, 12–18 weeks for an L-shape or hip-to-gable, and 14–20 weeks for a mansard. LB Wandsworth processes PD-route Lawful Development Certificates in approximately 8 weeks.
What does a loft conversion add to Putney property values?
In SW15, a well-executed loft conversion typically adds 15–25% to property value — often more in prime postcodes. The ROI is strongest when you add a double bedroom plus en-suite, which is the standard L-shape dormer configuration. Property uplift on a £44k–£216k build commonly exceeds the build cost by 30–60%.
