Loft conversion cost
in Wimbledon.
Wimbledon — SW19 — south-west London with a mix of village character around the common and Victorian/Edwardian terraces on the slopes below. Strong loft-conversion demand from family buyers.
What makes loft work in Wimbledon distinct.
Housing: Edwardian terraces and semis on the slopes, Victorian villas around the village, and 1920s/30s housing on the southern fringes.
Planning: Wimbledon Village, John Innes and Hartfield Road conservation areas cover specific pockets. Most of central SW19 retains PD rights.

What Wimbledon homeowners ask us.
Do I need planning permission for a loft in Wimbledon?
Wimbledon Village, John Innes and Hartfield Road conservation areas cover specific pockets. Most of central SW19 retains PD rights. Outside conservation areas, most rear-dormer conversions in Wimbledon 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.
Is Wimbledon a good loft market for return on investment?
Yes — the family buyer demand pushes property values up sharply once you add a bedroom and bathroom. Typical ROI on a well-executed L-shape dormer is 130–180%, with the strongest returns on the slopes between Wimbledon Park and the village.
How long does a Wimbledon loft conversion take?
Typical timeline: 6–10 weeks for design and planning (longer in conservation areas like much of Wimbledon), 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 Merton processes PD-route Lawful Development Certificates in approximately 8 weeks.
What does a loft conversion add to Wimbledon property values?
In SW19, 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 £42k–£205k build commonly exceeds the build cost by 30–60%.
