Wraparound extension in Perth
An L-shaped extension that fills the side return and runs across the back. If you live in Perth and want to know what a wraparound extension would cost and whether it needs planning, start with the online guide price or a free site visit.
We cover Perth (PH1 and PH2) as part of our Perth and Kinross work. In Perth we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

How much does a wraparound extension cost in Perth?
A wraparound extension in Perth is priced at £2,090–£3,420 per square metre including VAT as a guide, before kitchen fit-out and fees. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £46,000–£75,000 |
| L-shaped, about 30 m² of new floor | £62,500–£102,500 |
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 wraparound extension in Perth?
Here is how the rules in Scotland apply to a wraparound extension in Perth.
In Scotland side extensions are more restricted than rear ones under householder permitted development, and wraparounds generally need planning permission. A building warrant is required before work starts.
Scotland has no Party Wall Act. Work to shared walls is governed by property law and the title deeds, so we agree access and protection with neighbours in writing before work begins.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Perth like to extend?
Perth has sandstone tenements, terraced houses and villas closer in, with post-war semis and newer estates further out. Tenement and other flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Wraparound extension questions in Perth
How long does a rear extension take to build in Perth?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
Will it take a lot of garden?
Less than a deep rear extension of the same area, because part of the space comes from the side passage.
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 Perth free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do you handle building control in Perth?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
