Glazed and glass-box rear extensions in Shropshire
Full-height glass, slim frames and big rooflights for the most open rear room. Rear extensions in Shropshire: we cover 10 towns including Telford, Shrewsbury and Wellington, with design, approvals and the build under one contract.
If your garden in Telford faces south, expect us to talk about overhangs and solar-control glass before frame colours. Shropshire has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
How much does a glazed rear extension cost in Shropshire?
For Shropshire we work from the West Midlands rate: £2,800–£4,800 per square metre of new floor, including VAT, standard specification. The West Midlands is the baseline for our guide prices.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £33,500–£57,500 |
| 4 m wide × 6 m deep (24 m²) | £67,000–£115,000 |
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 Shropshire?
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres 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.

FAQ
Questions people ask
Will a glass extension be too hot?
Not if it is designed for its orientation, with solar-control glass, shading and ventilation.
Is there a limit on how much glass I can have?
In England the simple rule is 25% of the floor area plus openings removed; more is allowed with a calculation showing the house still meets Part L.
Sliding or bifold doors?
Sliders give bigger panes and slimmer sightlines; bifolds open the whole width. Our guide compares them.
