Homes in Crystal Palace and what suits them
Lambeth describes Gipsy Hill as piecemeal 19th-century suburban development rising up the hill. Around Crystal Palace you'll find Victorian terraces, semi-detached villas and later houses, many on sloping plots that need careful design for rear extensions.
Planning in Crystal Palace
- Crystal Palace sits at the edge of five London boroughs: Croydon, Bromley, Lambeth, Southwark and Lewisham. Croydon Council notes that the shopping area known as the Triangle is managed by Croydon, Bromley and Lambeth on different sides. The right council depends on your exact address, so we confirm it first.
- Conservation areas include Upper Norwood Triangle (Croydon), Westow Hill and Gipsy Hill (Lambeth), and Crystal Palace Park (Bromley).
- Outside conservation areas, many rear dormers and single-storey rear extensions can be built under permitted development; inside them, roof extensions usually need planning permission.
How we work in Crystal Palace
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.

Crystal Palace: questions homeowners ask
Do I need planning permission for a loft conversion in Crystal Palace?
Outside conservation areas, many rear dormers are permitted development. In Upper Norwood Triangle, Westow Hill, Gipsy Hill or other conservation areas, a loft usually needs planning permission.
Which council handles planning in Crystal Palace?
It depends on your street: Crystal Palace is split between Croydon, Bromley, Lambeth, Southwark and Lewisham councils. We check your address before preparing the application.
How long does a loft conversion or extension take in Crystal Palace?
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.
