Earlsfield loft FAQ

What Earlsfield homeowners ask us.

Do I need planning permission for a loft in Earlsfield?

Magdalen Park Conservation Area covers a specific pocket; most of Earlsfield retains PD rights. Outside conservation areas, most rear-dormer conversions in Earlsfield 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.

How long does an Earlsfield loft conversion take?

Typical timeline: 8 weeks for a Lawful Development Certificate, 6 weeks design and contract, then 10–14 weeks on site for a standard L-shape dormer. Total clock-time from first call to handover is usually around 6 months.

How long does a Earlsfield loft conversion take?

Typical timeline: 6–10 weeks for design and planning (longer in conservation areas like much of Earlsfield), 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 Earlsfield property values?

In SW18, 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%.
