Half Dormer Loft Conversions
Whatever form they take a half dormer will generally do two things:
Increase the amount of natural light
Increase the available headroom
They can also make a property more visually appealing if the traditional designs are used. The typical wide box dormer, whilst very practical, wouldn’t win many architectural design awards.
Traditional dormers, or half dormers, are usually found in three forms:
Flat Roof
Gable
Hip
Flat Roof Dormer
The most convenient dormer to build as the flat roof structure is far easier to install than the pitched roofs of other dormers.
The flat roof is sometimes inclined to do away with the need for guttering and is usually covered with lead or roofing felt.
Gable Dormer
The most common and aesthetically pleasing of dormers as this style makes up the majority of ‘chocolate box’ types as discussed here.
Built with a double pitched roof, the angle of which is usually identical to the pitch of the principal roof on the property, the structure of the dormer is fixed to the rafters within the roof space.
Hip Dormer
Similar to a gable dormer except with a hip end this style of half dormer is best used when the principal roof is of the hip variety.
This style is usually used when a hip-to-gable conversion is not possible and a side dormer needs to be incorporated into the design.
No Half Dormer At All!
Flat Roof Loft Conversion
A very common, and simple, conversion is to use the existing roof space, where sufficient, and include flush fitting roof light windows built into the slope of the roof. This style of loft conversion is both easy to plan and build and involves no alteration to the existing roof other than the installation of one or more windows.
Because this style of conversion relies on not altering the existing roof space they are usually only an option for older houses built with a truss and rafter roof structure or new homes built with an attic truss roof specification.
