Glazed rear extension in Halifax
For homes in Halifax, 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.
Halifax is covered from our West Yorkshire round, including HD6, HX1, HX2 and HX3. Glass-led rear extensions in Halifax are planned around which way the garden faces, because that decides the glass specification.

Do you need planning permission for a glazed rear extension in Halifax?
Whether your glazed rear extension in Halifax needs a planning application depends on its size, your house and any local restrictions.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Halifax like to extend?
Stone terraces and brick semis are typical of Halifax. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.

Glazed rear extension questions in Halifax
How much does a glazed rear extension cost in Halifax?

Can you match the brick or stone on my Halifax house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

The same rules apply as any rear extension; glass does not change the depth or height limits.

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