Do extensions in Stranraer need planning permission?
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.
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.
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.
Stranraer and surrounding towns
Site visits are available across Stranraer (DG9). We also work in nearby Dumfries (57 miles), Annan (71 miles). Ayr, in Ayrshire, is roughly 43 miles from Stranraer and also on our list.
Which extension suits a Stranraer home?
Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Start by comparing orangery extensions, bungalow extensions and single-storey rear extensions: between them they cover most of the layouts we see requested for houses like these.
