Rear extension planning drawings in Irvine
Measured survey, design options, planning drawings and the application, handled for you. We design, get the approvals for and build rear extensions in Irvine and the surrounding area, with one contract from the first survey to building control sign-off.
Irvine is covered from our Ayrshire round, including KA11 and KA12. For Irvine homes we start with a measured survey, then draw options before anything is submitted.

What do rear extension planning drawings cost in Irvine?
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. These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a rear extension in Irvine?
The planning route for a rear extension in Irvine is set by Scotland's householder rules and your council.
Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.
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. 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 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
Rear extension planning drawings questions in Irvine
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 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.
Can I see the design in 3D?
Yes; we produce simple 3D views so you can judge the size and light.
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.
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.
Do you handle building control in Irvine?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
