What works best for Paisley houses?
Scotland's housing includes sandstone villas, terraces and tenements in the cities and plenty of post-war and modern houses and bungalows elsewhere. A building warrant is needed before work starts.
Depending on the plot, orangery extensions and single-storey rear extensions are often the strongest options, with bungalow extensions worth considering where there is room.
Do extensions in Paisley need planning permission?
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.
In a conservation area or national scenic area the householder permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition or direction, any extension needs an application.
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.

Questions about extensions in Paisley
How much does an extension cost in Paisley?
Using our Scotland factor (×0.98), a standard-spec single-storey extension of 20 m² is a guide £40,000 to £51,000 including VAT, and a 32 m² two-storey extension £56,000 to £74,000. Your written price follows the survey.
Do I need planning permission for an extension in Paisley?
Not always. It depends on the size, position and your property's history. Scottish householder rules allow some smaller extensions without an application, but a building warrant is still needed.
Do you handle building regulations?
Yes. We prepare the drawings and calculations, submit them and book inspections, and in Scotland we apply for the building warrant before work starts.
Do you cover all of Paisley?
Yes, including the surrounding parts of Renfrewshire and Inverclyde. Site visits are free and there is no obligation.
Can I get a price before anyone visits?
Yes. This page shows guide prices adjusted for Paisley, and the guide-price tool gives a range for your own size and finish in about a minute.
