What do rear extension planning drawings cost in Troon?
As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. Planning and building warrant fees in Scotland are set nationally and by value of work; we confirm both before submitting. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a rear extension in Troon?
The planning route for a 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.
Scottish councils aim to decide householder applications within two months; the building warrant runs alongside.
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 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.

We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.
Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.
Planning and regulations
We take the design through the right planning route, then produce the construction drawings and engineer's calculations for the building warrant.

FAQ
Rear extension planning drawings questions in Troon
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.
Do I need an architect?
You need accurate drawings by someone who knows householder planning; we provide them.
How long does a rear extension take to build in Troon?
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 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.
Is the site visit in Troon free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
