Dormer loft conversions in the Highlands

Covering The Highlands

Our coverage across the Highlands includes Inverness, Fort William, Nairn and Thurso.

Because the Highlands covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.

Homes in the Highlands

Housing in Scotland includes tenements in the cities, sandstone villas, inter-war and post-war semis and a large number of bungalows, which often suit dormer and upward extensions.

What do you get with a dormer loft conversion?

A dormer loft conversion builds a box-shaped extension out from the rear slope of the roof, creating vertical walls and full head height across most of the new floor. It is the most popular type of loft conversion because it gives the most usable space for the cost.

How much should I budget for a dormer loft conversion?

Use these ranges to budget for dormer loft conversions; the survey turns them into a fixed price for the agreed specification.

Dormer loft conversions	Guide price incl. VAT
Rear dormer, bedroom only	£50,000 to £65,000
Full-width dormer with en-suite	£60,000 to £80,000
L-shaped dormer (over rear outrigger)	£65,000 to £90,000

What approvals does a dormer loft conversion need in Scotland?

In Scotland the key step is the building warrant, which must be granted before work begins. Planning permission is decided separately by the council, and work on shared walls is handled under your title deeds rather than a party wall act.

In Scotland, dormers and other roof enlargements usually need planning permission, especially on the front of the house.

What can affect a dormer loft conversion?

A flat dormer roof needs proper falls and a quality membrane.
L-shaped dormers are common on Victorian terraces with a rear outrigger.
