Rear extension plans and planning applications in Perth and Kinross
Measured survey, design options, planning drawings and the application, handled for you. Across Perth and Kinross we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Perth, Blairgowrie and Rattray and Crieff.
Planning applications in Perth go to the local planning authority, and we check its local design guidance for rear extensions before drawing. Perth and Kinross 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.
What does it cost in Perth and Kinross?
As a guide, £1,000–£2,500 including VAT. 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 in Perth and Kinross?
In Scotland an extension of more than one storey is only permitted development (Class 1B) if no part is within 10 metres of any boundary and it is no higher than the existing house, so almost every two-storey rear extension needs planning permission and a building warrant.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.
Planning and building warrant fees in Scotland are set nationally and by value of work; we confirm both before submitting.
Scottish councils aim to decide householder applications within two months; the building warrant runs alongside.
