Dormer loft conversion

loft conversion image
A dormer could be an extension to the existing roof, allowing additional floor space and headroom within the existing loft conversion. Dormers protrude from the roof slope, normally at the rear of the property and can be built in a variety of styles. Internally, a dormer will have a horizontal ceiling and vertical walls compared to the normal diagonal sides of conversion. In those lofts that have limited space or headroom a dormer will provide additional space that can make a conversion more feasible.

Dormers are built in a variety of shapes, including flat, shed, gabled, pedimented, hipped, deck, arched, oval, eyebrow, inset and composite, a type that includes several forms. Flat roof dormers tend to provide the maximum amount of additional internal space although they do not look attractive from outside. Gable fronted and hipped roof dormers look much more attractive but they often do not give much internal space and will cost more to build due the extra complexity.

You will need to be aware that in some areas you may not be allowed to have dormers in your loft conversion. You will need to check with your local planning department to get the rules for your area. If your builder has worked in your area before he will probably be able to give an indication as to what may be allowed.
There are different types of dormer:
Gable Roof Dormers
Not usually needing planning permission and usually the best option with terraced houses, we adapt an existing pitched roof for maximum extra space so you get vertical windows and plenty of extra space plus the extra storage space you get when all the nooks and crannies are made into shelves and cupboards.
Hip Roof Dormer
The hip roof dormer is similar to the gable roof dormer in terms of its general structure but roof design is different. It has three sloping planes that connect to the center ridge beam instead of two. Hip roofs, in general, are a good choice for regions prone to hurricanes or high winds. On the downside, they offer less space as a result of the sloping plane on the front side and are the most complex to construct.
Shed Roof Dormer
The shed roof dormer has a single sloping plane, making it the simplest of all four designs. Another benefit of the shed roof dormer is that it is the most cost-efficient option in comparison to the other three types.
Arched Dormer
The arched roof dormer is the fourth basic type of roof dormer. As the name implies, it has an arched roof. This type also contains the weight-bearing walls as the other three styles. Arched roof dormers give structures a period look because they were popular elements in French architectural design.
