In Scotland many families extend bungalows and semis, while tenement flats bring shared ownership of roofs and walls that needs agreeing early.

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 is a dormer loft conversion approved in Fort William?

Scottish projects follow a different process from England: the council issues a building warrant before work starts and accepts a completion certificate at the end, alongside any planning permission needed. We prepare both applications.

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

What should I think about before starting?

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

How does the project run?

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
