What goes into 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.
- Planning and building control applications to the council
- Steelwork and new floor structure

How is a dormer loft conversion approved in Cookstown?
Projects in Northern Ireland need planning clearance from one of the eleven councils and building control approval, also from the council. The Party Wall etc. Act does not extend to Northern Ireland, so work near neighbours is agreed directly and documented carefully.
In Northern Ireland, roof enlargements such as dormers often need planning permission depending on size and position. Building control approval is needed for every loft conversion.
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.
