Do you need planning permission for a bungalow rear extension in Kilmarnock?
Planning for a bungalow rear extension in Kilmarnock 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.
Scotland has no larger-extension prior approval route; extensions beyond permitted development need a planning application.
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 Kilmarnock like to extend?
Kilmarnock 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.

FAQ
Bungalow rear extension questions in Kilmarnock
What postcode areas do you cover around Kilmarnock?
Including KA1, and the surrounding Ayrshire area.
Can you match the brick or stone on my Kilmarnock house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
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 Kilmarnock?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
