Homes in Putney and what suits them
Putney's period terraces and semi-detached houses suit rear and hip-to-gable dormer lofts and full-width or side-return kitchen extensions. Wandsworth's East Putney appraisal points to oversized dormers as harmful to the street, so dormer size and design matter here.
Planning in Putney
- Putney is in the London Borough of Wandsworth, so applications go to Wandsworth Council.
- Conservation areas include East Putney, West Putney, Putney Embankment and Putney Lower Common.
- On Putney Lower Common, an Article 4 direction covers 15–36 Commondale: enlarging or altering these houses, including roof changes visible from a road, needs planning permission.
- Outside conservation areas, many rear dormers and single-storey rear extensions can be built under permitted development.
How we work in Putney
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.

Putney: questions homeowners ask
Do I need planning permission for a loft conversion in Putney?
Outside conservation areas, many rear dormers are permitted development. In the East Putney, West Putney, Putney Embankment or Putney Lower Common conservation areas you need planning permission, and Wandsworth looks closely at dormer size.
Which council handles planning in Putney?
Wandsworth Council handles planning and building control for Putney.
How long does a loft conversion or extension take in Putney?
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.
