Homes in Herne Hill and what suits them

Much of Herne Hill was built up in the late Victorian and Edwardian years, with streets of terraced and semi-detached houses. These usually suit a rear or L-shaped dormer loft, and a rear or side-return kitchen extension at the back.

Planning in Herne Hill

Herne Hill sits across two councils, Lambeth and Southwark. We check which council your home is in before we draw anything.
Lambeth has a Herne Hill conservation area (CA61), described by the council as mostly commercial and residential development from around 1900. In a conservation area, loft dormers need full planning permission.
Outside conservation areas, many rear dormers and single-storey rear extensions can be built under permitted development.

How we work in Herne Hill

Our in-house team does the measured survey, drawings and the planning or permitted-development application through Plan It, then manages the build with a single project lead. Party wall agreements are handled through our partner surveyors. Typical build times: rear dormer 10–12 weeks, L-shaped dormer 12–14 weeks, mansard 12–16 weeks, rear extension 12–16 weeks.

Herne Hill: questions homeowners ask

Do I need planning permission for a loft conversion in Herne Hill?

Outside conservation areas, many rear and L-shaped dormers in Herne Hill can be built under permitted development within the size limits. In a conservation area, dormers need full planning permission.

Which council handles planning in Herne Hill?

Lambeth Council or Southwark Council, depending on which side of the borough boundary your home is. We check this before we start the drawings.

How long does a loft conversion or extension take in Herne Hill?

Most of our lofts take 10–16 weeks on site and most rear extensions 12–16 weeks, depending on the design. If you need planning permission, allow around 8 weeks for the council's decision on a householder application, plus time to prepare the drawings.

Can you design it as well as build it?

Yes. Our Plan It service covers the measured survey, drawings and the planning or permitted-development application. You can stop there, or carry straight on to the build with the same team.
