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.
Planning rules for 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.
Scottish extensions are approved by building warrant, granted by the council's building standards team before work begins, with a completion certificate submitted when the work is finished.
