Two-storey rear extension in Troon
Two-storey rear extension in Troon: a larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We measure the house, show you what the rules allow, price it in writing and build it.
We cover Troon (KA10) as part of our Ayrshire work. Two-storey rear extensions suit semi-detached houses in Troon best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Troon?
The planning route for a two-storey rear extension in Troon is set by Scotland's householder rules and your council.
In Scotland an extension of more than one storey is only permitted development (Class 1B) if no part is within 10 metres of any boundary and it is no higher than the existing house, so almost every two-storey rear extension needs planning permission and a building warrant.
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 Troon like to extend?
Post-war semis and terraces are common around Troon, and many have room for a single-storey rear extension within Class 1A limits.

Two-storey rear extension questions in Troon

Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.

Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can you match the brick or stone on my Troon house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
