Loft conversions fall into one of four basic types, which type you decide to use for your conversion will depend on many factors, such as
the design of your existing roof, your budget, planning restrictions and your own personal preferences. There is also the Party Wall Act
1996 to consider. If you do not inform your neighbours about what you intend to do they could stop the work.
Velux and rooflight conversions are the same. Velux are the leading manufacturer of roof windows.
With over 60 years experience producing windows the name Velux has become synonymous with
this type of conversion. It is generally very cost effective and does not normally need planning
A dormer is an extension to the existing roof, allowing for additional floor space and headroom
within the loft conversion. Dormers protrude from the roof slope, normally at the rear of the
property, and can be built in a variety of styles. In lofts that have limited space or headroom a dormer
will provide additional space that can make a conversion feasible.
A mansard roof has two slopes, the lower slope is close to vertical at 72 degrees and the top section
of the roof is almost horizontal. This style of roof is named after a 17th-century French architect
Francois Mansart (1598-1666) who used this design of roof on many of his buildings. A mansard roof
has the advantage of maximising the available space within your loft.
Hip to Gable
A hip to gable conversion involves making fairly major changes to the roof. The gable wall is built up
to the ridge line and a new section of roof is built to fill in the gap. As a general rule, houses with hip
roofs tend not to have enough internal volume for a conversion to be practical. So a hip to gable
conversion is the best solution.
