Extensions in and around Paisley
Our survey diary covers Paisley, including G78, PA1, PA2, PA3, PA4, PA5. The same team covers Barrhead (3 miles), Renfrew (3 miles), Johnstone (3 miles), Erskine (5 miles), all within easy reach.
Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Planning rules that apply in Paisley
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted.
Homes in conservation areas, national scenic areas and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Applications are decided by your council as planning authority.

Utility room extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Paisley, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Paisley?
Yes. We cover Paisley and the surrounding parts of Renfrewshire and Inverclyde. Site visits are free and there is no obligation.
Will my neighbours in Paisley be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
Does a utility extension need planning permission?
Often not, if it is single storey and within permitted development limits. We check this for your property.

Our guide range is about £1,860 to £3,430 per m² including VAT, with a minimum of around £14,000. An 8 m² standard-spec utility is typically £17,500 to £22,000 in Paisley.
