Planning rules that apply in Cumbernauld
In Scotland a small porch can be permitted development (Class 1C) within limits on floor area, height and distance from a road; larger porches need planning permission, and building standards still apply, so we check whether a building warrant is needed.
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.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Applications are decided by your council as planning authority.
