Glazed rear extension in Sale

For homes in Sale, a glazed rear extension is often the simplest way to gain space without moving. Full-height glass, slim frames and big rooflights for the most open rear room. We take it from survey to completion certificate.

Sale is covered from our Greater Manchester round, including M32, M33 and M41. If your garden in Sale faces south, expect us to talk about overhangs and solar-control glass before frame colours.

3 m wide × 4 m deep (12 m²)£31,500–£54,000
4 m wide × 6 m deep (24 m²)£63,000–£108,500

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

Do you need planning permission for a glazed rear extension in Sale?

Planning for a glazed rear extension in Sale follows the English householder rules.

Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.

New fabric must meet Approved Document L (2021 edition incorporating 2023 amendments): walls 0.18, roof 0.15 and floor 0.18 W/m²K, windows 1.4 W/m²K or Band B. Under the simple route, new windows, doors and rooflights should not exceed 25% of the extension floor area plus any openings removed; more glass is possible with a whole-house calculation.

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 Sale like to extend?

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

FAQ

Glazed rear extension questions in Sale

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

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

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

Is a glass box a conservatory?

No. It is built to Building Regulations as part of the house, with insulated floor and roof, so it is usable all year.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

Do I need planning permission for a rear extension in Sale?

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.

Can you match the brick or stone on my Sale house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
