Local to Larkhall

Newton Mearns, in Renfrewshire and Inverclyde, is roughly 15 miles from Larkhall and also on our list. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.

Will the council need to approve it?

In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted.

Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.

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.

In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.

Applications are decided by your council as planning authority.
