What Herne Hill homeowners ask us.
Do I need planning permission for a loft in Herne Hill?
Herne Hill Conservation Area covers most of the central streets. Article 4 applies in places. Outside conservation areas, most rear-dormer conversions in Herne Hill 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 loft work in Herne Hill split between two councils?
Yes — the boundary between LB Lambeth and LB Southwark runs through Herne Hill, so your planning application goes to one or the other depending on the exact street. We check the address before quoting; both councils handle PD-route LDCs efficiently.
How long does a Herne Hill loft conversion take?
Typical timeline: 6–10 weeks for design and planning (longer in conservation areas like much of Herne Hill), 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 Lambeth & LB Southwark processes PD-route Lawful Development Certificates in approximately 8 weeks.
What does a loft conversion add to Herne Hill property values?
In SE24, 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 £43k–£209k build commonly exceeds the build cost by 30–60%.
