Larger home extension prior approval (England) in Warwickshire
Up to 6 m (attached) or 8 m (detached) deep, after neighbour consultation. Across Warwickshire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Nuneaton, Rugby and Royal Leamington Spa.
Warwickshire has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
How much does a prior approval rear extension cost in Warwickshire?
In Warwickshire, our guide for a prior approval rear extension is £1,900–£3,100 per square metre including VAT for a standard specification. The West Midlands is the baseline for our guide prices.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £23,000–£37,000 |
| 4 m wide × 5 m deep (20 m²) | £38,000–£62,000 |
| 4 m wide × 6 m deep (24 m²) | £45,500–£74,500 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission in Warwickshire?
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.
