Larger home extension prior approval (England) in Worcestershire
Up to 6 m (attached) or 8 m (detached) deep, after neighbour consultation. We design and build rear extensions across Worcestershire, from Worcester and Redditch to Kidderminster, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Red-brick terraces and 1930s semis make up much of Worcestershire. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
How much does a prior approval rear extension cost in Worcestershire?
Guide prices for a prior approval rear extension in Worcestershire start from our West Midlands rate of £1,900–£3,100 per square metre, including VAT. 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 Worcestershire?
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.
