Not sure which loft conversion suits your home? We compare the four most common types and what each one offers.
Velux (rooflight) conversion
A Velux conversion keeps the existing roof shape and adds rooflights to bring in daylight. It is usually the simplest and most affordable option, but it needs a loft with good head height to start with.
Dormer conversion
A dormer is a box-shaped structure built out from the slope of the roof, usually at the rear. It creates a large amount of usable floor space and full head height, which makes it the most popular choice for terraced and semi-detached homes in Birmingham.
Hip-to-gable conversion
If your house has a sloping (hipped) side roof, a hip-to-gable conversion straightens it into a vertical gable wall. This adds space where the staircase can land and is often combined with a rear dormer.
Mansard conversion
A mansard conversion changes the roof slope to an almost vertical angle and flattens the top. It provides the most space but involves the most structural work and usually needs planning permission.
Which one is right for you?
The best option depends on several factors, including:
- The height of your loft from the floor joists to the ridge (ideally at least 2.2 metres)
- The type and pitch of your roof
- Where the new staircase can go
- Your budget and how you want to use the room
- Whether your property has permitted development rights
