Dormers are becoming more common in homes as they can help create extra headroom in spaces that may otherwise be too small or too low for habitation. They enable the creation of rooms in the roof or loft without needing to construct a new storey. Dormers will typically have dormer windows set into them to allow light and ventilation.
There are a number of different types of dormers including:
Hip roof: The roof comprises of three sloping panels that meet at the ridge.
The insertion of dormer windows as part of a loft conversion does not normally require planning permission. However, If the roof space is altered or extended and it exceeds specified limits and conditions, permission may be necessary. It may also be necessary to obtain permission within conservation areas, National Parks, Areas of Outstanding Natural Beauty or the Broads, or if the building is listed.
Dormer windows may require building regulations approval.
