Single-storey rear extension in Leyland

For homes in Leyland, a single-storey rear extension is often the simplest way to gain space without moving. Ground-floor space across the back of the house, usually for a kitchen, dining or family room. We take it from survey to completion certificate.

Leyland and its postcode districts PR25 and PR26 are part of our Lancashire coverage. A single-storey rear extension in Leyland is mostly built from the garden side, so the house stays usable for most of the job.

Do you need planning permission for a single-storey rear extension in Leyland?

The planning route for a single-storey rear extension in Leyland is set by England's householder rules and your council.

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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in Leyland like to extend?

Stone and brick terraces are common around Leyland. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

How a single-storey rear extension in Leyland comes together

  1. Survey visit

    We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.

  2. Drawings and budget

    Floor plans and elevations for the options, each with a guide price.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.

  4. Build and sign-off

    We build to the approved drawings with regular updates, then hand over the building control completion certificate and any guarantees from suppliers.

FAQ

Single-storey rear extension questions in Leyland

Do you handle building control in Leyland?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

How long does a rear extension take to build in Leyland?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Is a flat roof or a pitched roof better?

A warm flat roof keeps the extension low under first-floor windows and suits a roof lantern; a pitched or lean-to roof gives a vaulted ceiling. Both last for decades when built properly.

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
