Do you need planning permission for a wraparound extension in Grangemouth?
Planning for a wraparound extension in Grangemouth follows the Scottish householder rules.
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. 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 Grangemouth like to extend?
Post-war semis and terraces are common around Grangemouth, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Wraparound extension questions in Grangemouth
How long does a rear extension take to build in Grangemouth?
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.
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.
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 you match the brick or stone on my Grangemouth house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
