Do you need planning permission for a glazed rear extension in St Andrews?
The planning route for a glazed rear extension in St Andrews is set by Scotland's householder rules and your council.
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 St Andrews like to extend?
Post-war semis and terraces are common around St Andrews, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Glazed rear extension questions in St Andrews
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Do you handle building control in St Andrews?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
Is a glass box a conservatory?
No. It is built to Building Regulations as part of the house, with insulated floor and roof, so it is usable all year.
Can you match the brick or stone on my St Andrews house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Many single-storey rear extensions are permitted development under Class 1A, but not in conservation areas; you always need a building warrant before work starts.

Yes. We visit, measure up and talk through the options with no cost and no obligation.
