Do you need planning permission for a wraparound extension in Renfrew?
The planning route for a wraparound extension in Renfrew is set by Scotland's householder rules and your council.
Scottish householder rights treat the side part of a wraparound or side infill more strictly than a plain rear extension, so most need planning permission, and all need a building warrant.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
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 Renfrew like to extend?
Renfrew has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Wraparound extension questions in Renfrew
How much does a wraparound extension cost in Renfrew?
As a guide, £2,090–£3,420 per square metre including VAT for a standard specification. For example, L-shaped, about 22 m² of new floor: about £46,000–£75,000 at that rate. Your written price follows the survey.
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.
What roof suits a wraparound?
A flat roof with a lantern, a standing-seam pitched roof or a glazed roof over the side leg. The choice usually follows the first-floor windows above.
Do I need planning permission for a rear extension in Renfrew?
Many single-storey rear extensions are permitted development under Class 1A, but not in conservation areas; you always need a building warrant before work starts.
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.
Is the site visit in Renfrew free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
