Glazed rear extension in Irvine
Glazed rear extension in Irvine: full-height glass, slim frames and big rooflights for the most open rear room. We measure the house, show you what the rules allow, price it in writing and build it.
We cover Irvine (KA11 and KA12) as part of our Ayrshire work. Glass-led rear extensions in Irvine 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 Irvine?
Planning for a glazed rear extension in Irvine follows the Scottish householder rules.
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. 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 Irvine like to extend?
Post-war semis and terraces are common around Irvine, and many have room for a single-storey rear extension within Class 1A limits.
