Do you need planning permission for a single-storey rear extension in Prestwick?
Here is how the rules in Scotland apply to a single-storey rear extension in Prestwick.
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.
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. 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 Prestwick like to extend?
Post-war semis and terraces are common around Prestwick, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Single-storey rear extension questions in Prestwick
Do I need planning permission for a rear extension in Prestwick?
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.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
Can I stay in the house during the build?
Usually yes. The noisiest, dustiest stage, removing the back wall, is kept to the final weeks and screened off. Most families set up a temporary kitchen elsewhere in the house.
How long does a rear extension take to build in Prestwick?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Is the site visit in Prestwick free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
