In Scotland many families extend bungalows and semis, while tenement flats bring shared ownership of roofs and walls that needs agreeing early.
What is 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.
- Building warrant application and completion certificate
- Steelwork and new floor structure
- Dormer frame, roof covering and cladding

Planning and building rules in Kilmarnock
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. A building warrant is needed before work starts in every case.
What can change the price or programme?
- A flat dormer roof needs proper falls and a quality membrane.
- L-shaped dormers are common on Victorian terraces with a rear outrigger.
What are the steps?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
