What are homes in Nairn like to extend?
Traditional stone houses sit alongside modern bungalows and timber-frame homes around Nairn. A lighter, contrasting addition at the back often suits older stone houses better than trying to copy the walling.
Planning rules for Nairn
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.
