Choosing the right extension in Stornoway
Scotland's housing includes sandstone villas, terraces and tenements in the cities and plenty of post-war and modern houses and bungalows elsewhere. A building warrant is needed before work starts.
Start by comparing double-storey extensions, orangery extensions and bungalow extensions: between them they cover most of the layouts we see requested for houses like these.
Where we work near Stornoway
Site visits are available across Stornoway (HS1). Island and remote projects are planned individually, with travel, deliveries and accommodation for the team agreed before the survey.
Do extensions in Stornoway 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.
