What do rear extension planning drawings cost in Perth?

As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. Planning and building warrant fees in Scotland are set nationally and by value of work; we confirm both before submitting. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

Do you need planning permission for a rear extension in Perth?

Whether your rear extension in Perth needs a planning application depends on its size, your house and any local restrictions.

Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.

Scottish councils aim to decide householder applications within two months; the building warrant runs alongside.

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 Perth like to extend?

Perth has sandstone tenements, terraced houses and villas closer in, with post-war semis and newer estates further out. Tenement and other flats need planning permission for an extension, and every project needs a building warrant before work starts.
