Glazed rear extension in Bonnyrigg
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 Bonnyrigg and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Bonnyrigg (EH18, EH19 and EH24) as part of our Edinburgh and the Lothians work. If your garden in Bonnyrigg faces south, expect us to talk about overhangs and solar-control glass before frame colours.

Do you need planning permission for a glazed rear extension in Bonnyrigg?
Here is how the rules in Scotland apply to a glazed rear extension in Bonnyrigg.
Scottish householder permitted development (Class 1A) covers many single-storey rear extensions, with a 3 metre eaves limit, a 4 metre height limit and, within 1 metre of a boundary, a depth limit of 3 metres for terraced houses or 4 metres for others. Conservation areas are excluded, and you need a building warrant whatever the planning position.
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. 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 Bonnyrigg like to extend?
Bonnyrigg 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.
