Loft conversion cost
in West Kensington.
West Kensington — the W14 streets north of Talgarth Road. Mansion blocks dominate the main roads; behind them is a grid of late-Victorian and Edwardian terraces with strong loft potential.
What makes loft work in West Kensington distinct.
Housing: Late-Victorian terraces with tile-hung gables and outriggers, plus large red-brick mansion blocks on the main roads.
Planning: Parts of W14 fall within Edith Road Conservation Area and Olympia Conservation Area — these need full planning, while the eastern blocks toward Earls Court Road often retain PD rights.
Applications go to LB Hammersmith & Fulham. We submit on your behalf and handle conservation officer correspondence end-to-end.

What West Kensington homeowners ask us.
Do I need planning permission for a loft in West Kensington?
Parts of W14 fall within Edith Road Conservation Area and Olympia Conservation Area — these need full planning, while the eastern blocks toward Earls Court Road often retain PD rights. Outside conservation areas, most rear-dormer conversions in West Kensington 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.
Can a mansion-block flat have a loft conversion in West Kensington?
Top-floor flats in mansion blocks can — but you need (1) the freeholder's consent in writing, (2) party wall awards from neighbouring flats below, and (3) usually full planning even if the block isn't in a conservation area. Costs are typically 25–40% higher than a terraced loft because of access and scaffold logistics.
How long does a West Kensington loft conversion take?
Typical timeline: 6–10 weeks for design and planning (longer in conservation areas like much of West Kensington), 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 Hammersmith & Fulham processes PD-route Lawful Development Certificates in approximately 8 weeks.
What does a loft conversion add to West Kensington property values?
In W14, 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 £49k–£238k build commonly exceeds the build cost by 30–60%.
