Planning and building rules in Perth and Kinross
In Scotland a single-storey rear extension can be permitted development under Class 1A: eaves no higher than 3 metres and an overall height of 4 metres, and where any part is within 1 metre of a boundary it can project no more than 3 metres on a terraced house or 4 metres on other houses. The rights do not apply in conservation areas, and a building warrant is still needed before work starts.
Scotland has no larger-extension prior approval route; extensions beyond permitted development need a planning application.
In Scotland you need a building warrant from the council before any work starts, and a completion certificate accepted at the end. The design follows the Scottish Building Standards Technical Handbooks.
Scotland has no Party Wall Act. Work to shared walls is governed by property law and the title deeds, so we agree access and protection with neighbours in writing before work begins.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.
