West Yorkshire
Larger home extension prior approval (England) in West Yorkshire
Up to 6 m (attached) or 8 m (detached) deep, after neighbour consultation. We design and build rear extensions across West Yorkshire, from Leeds and Bradford to Huddersfield, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Stone terraces and brick semis are typical of West Yorkshire. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.
How much does a prior approval rear extension cost in West Yorkshire?
In West Yorkshire, our guide for a prior approval rear extension is £1,770–£2,880 per square metre including VAT for a standard specification. Yorkshire prices sit below our West Midlands baseline; matching natural stone is the main variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £21,000–£34,500 |
| 4 m wide × 5 m deep (20 m²) | £35,500–£57,500 |
| 4 m wide × 6 m deep (24 m²) | £42,500–£69,000 |
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 West Yorkshire?
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.
