Glazed rear extension in Motherwell
We plan and build glazed and glass-box rear extensions for homeowners in Motherwell. Full-height glass, slim frames and big rooflights for the most open rear room. Start with a free site visit, then a written price once the design is agreed.
Motherwell is covered from our Lanarkshire round, including ML1 and ML4. If your garden in Motherwell faces south, expect us to talk about overhangs and solar-control glass before frame colours.

How much does a glazed rear extension cost in Motherwell?

| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £32,000–£54,500 |
| 4 m wide × 6 m deep (24 m²) | £64,000–£109,500 |
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 Motherwell?
Whether your glazed rear extension in Motherwell needs a planning application depends on its size, your house and any local restrictions.
In Scotland a single-storey rear extension can be permitted development under Class 1A: eaves no higher than 3 metres and an overall height of 4 metres, and where any part is within 1 metre of a boundary it can project no more than 3 metres on a terraced house or 4 metres on other houses. The rights do not apply in conservation areas, and a building warrant is still needed before work starts.
Insulation and glazing follow Section 6 of the Scottish Technical Handbook; the building warrant drawings show how the extension meets it.
Classes 1A and 1B do not apply in conservation areas, and listed buildings 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 Motherwell like to extend?
Motherwell has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

Not if it is designed for its orientation, with solar-control glass, shading and ventilation.
