Do you need planning permission for a wraparound extension in Irvine?
Here is how the rules in Scotland apply to a wraparound extension in Irvine.
Scottish householder rights treat the side part of a wraparound or side infill more strictly than a plain rear extension, so most need planning permission, and all need a building warrant.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
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 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.

FAQ
Wraparound extension questions in Irvine
Do I need planning permission for a rear extension in Irvine?
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.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Can you match the brick or stone on my Irvine house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
