Fort William, Highlands and Islands
Terraced house rear extension in Fort William
Rear and side return extensions for terraces, with access through the house and two neighbours. We design, get the approvals for and build rear extensions for terraced houses in Fort William and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Fort William (PH33) as part of our Highlands and Islands work. Terraced streets make up much of the housing in parts of the Highlands and Islands, and most rear extensions here go in without side access.

| 3 m wide × 6 m deep (18 m²) | £35,000–£56,500 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a terraced house rear extension in Fort William?
Planning for a terraced house rear extension in Fort William follows the Scottish householder rules.
Scottish householder permitted development (Class 1A) covers many single-storey rear extensions, with a 3 metre eaves limit, a 4 metre height limit and, within 1 metre of a boundary, a depth limit of 3 metres for terraced houses or 4 metres for others. Conservation areas are excluded, and you need a building warrant whatever the planning position.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
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.
How a terraced house rear extension in Fort William comes together
Survey visit
We measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.
Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.
Planning and regulations
We take the design through the right planning route, then produce the construction drawings and engineer's calculations for the building warrant.
Written price, then build
Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ
Terraced house rear extension questions in Fort William
Do I need planning permission for a rear extension in Fort William?
Many single-storey rear extensions are permitted development under Class 1A, but not in conservation areas; you always need a building warrant before work starts.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
How do you keep the house clean?
Dust screens, floor protection and a single protected route through the house.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Do you handle building control in Fort William?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
