The type of loft conversion you can have depends on the type of property you live in.
Dormer
The dormer is a structure projecting from the roof slope,
which lets in additional light and ventilation to the loft
conversion. A dormer will also give additional headroom.
Rear Dormer
A rear dormer creates a square end to the back of your house
and has a flat roof. This creates a substantial amount of
extra floor space and height. It is possible on most terraced
and semi detached properties, and allows a greater choice of
rooms within the loft space. It is often possible to construct
a dormer without gaining planning permission. It will be
constructed to the rear of your loft room. The cheeks, together
with the front panel around the windows of the dormer will be
clad in tile or slate, the choice being dependent on how best
to retain the character of your home. The roof, although
appearing flat, will slope to the edge of the dormer to
allow rainwater to flow away freely.
Front Dormer — Side Dormer
These are smaller dormers constructed to be in-keeping with your property.
A side dormer is used to replace a hip to gable construction when planning
is required.
Hip to Gable
This involves changing the sloping side of your property, to a flat, gable
end, creating a much bigger loft room and often creating space for the staircase.
Mansard
This is another construction to the rear of your property which has a flat
roof, however, the back wall slopes inwards at an angle of 72 degrees and
windows are housed in small dormers. Normally constructed where planning
permission is required or your property falls into a conservation area.
On certain types of property, a mansard can give a more pleasing aesthetic
to the exterior, integrating the loft conversion into the existing architecture.
Velux
With this type of construction the roof line is unaltered and a room is simply
created in your existing loft space. This type of conversion lends itself to
Victorian style houses and is often used if Planning Permission is required.
