Do you need planning permission for a kitchen-diner rear extension in Fort William?
Here is how the rules in Scotland apply to a kitchen-diner rear extension in Fort William.
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.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Fort William like to extend?
Fort William has older stone houses, post-war homes and many detached houses and bungalows on larger plots. Wind and rain shape the design: roof pitch, cladding and glazing are chosen for the weather, and every extension needs a building warrant.
