Homes in Wimbledon and what suits them
Merton describes Wimbledon North as a spacious and verdant residential suburb of the 19th century and later. Larger semi-detached and detached houses here often suit hip-to-gable lofts and full-width rear extensions; terraces suit rear dormers and side returns.
Planning in Wimbledon
- Most of Wimbledon is in the London Borough of Merton, so applications go to Merton Council. Some SW19 streets near Southfields and Wimbledon Park are in Wandsworth.
- Merton's conservation areas here include Wimbledon Village, Wimbledon West, Wimbledon North and Wimbledon Hill Road. Loft dormers in a conservation area need planning permission.
- Outside conservation areas, many rear dormers and single-storey rear extensions can be built under permitted development.
How we work in Wimbledon
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.

Our work in Wimbledon
Wimbledon: questions homeowners ask
Do I need planning permission for a loft conversion in Wimbledon?
Outside conservation areas, many rear dormers are permitted development. In Wimbledon Village, Wimbledon West, Wimbledon North or Wimbledon Hill Road conservation areas you need planning permission.
Which council handles planning in Wimbledon?
Merton Council for most of Wimbledon; Wandsworth Council for some streets near Southfields and Wimbledon Park.
How long does a loft conversion or extension take in Wimbledon?
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.
