Glazed rear extension in Birstall
Full-height glass, slim frames and big rooflights for the most open rear room. We design, get the approvals for and build glazed and glass-box rear extensions in Birstall and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Birstall (LE1, LE4 and LE5) as part of our Leicestershire and Rutland work. Glass-led rear extensions in Birstall 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 Birstall?
The planning route for a glazed rear extension in Birstall 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.
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 Birstall like to extend?
