Kitchen-diner rear extensions in West Yorkshire

An open-plan kitchen, dining and family room that opens straight onto the garden. 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.

A kitchen-diner is often the reason people in Leeds extend: the back kitchen in stone terraces and brick semis is rarely big enough for a table. 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.

In West Yorkshire, our guide for a kitchen-diner 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.

Do you need planning permission in West Yorkshire?

In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.

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.

FAQ

Questions people ask

Should the sink face the garden?

If the plan allows, an island sink or hob facing the glass is a common choice. It needs a floor-level drain run, which is easy to lay in a new slab.

Can I have underfloor heating?

Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.

Where does the cooker extraction go?

Through the new wall or roof, ducted to outside. Recirculating hoods are possible but less effective.

Do you cover all of West Yorkshire?

We cover 38 towns and districts in West Yorkshire, including Leeds, Bradford and Huddersfield.

Who builds the extension?

Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
