Loft Conversion Types
There are 4 main types of loft conversion; Velux, Dormer, Gable End, and Mansard. While some loft conversions may fall into two categories, most loft conversions will have a single, distinct type.
Velux Loft Conversion
Velux loft conversions take their name from the rooflights installed as part of the conversion. This is the fastest and often the cheapest loft conversion type since there are no extensive changes to the exterior of the house. These conversions also rarely require planning permission as the changes to the outside of the house are so subtle.
Dormer Loft Conversion
Dormer loft conversions are one of the more popular loft conversion types. While the Dormers do project out from the pitch of the roof, these conversions do not involve extensive changes to the rest of the roof so the process for this kind of loft conversion is often allowed as a permitted development.
Dormer loft conversions get their name from the windows that jut out from the roof – there are a number of dormer styles, and they often provide more headroom than a standard Velux loft conversion.
Gable End Loft Conversion
Gable End loft conversions are only suitable for detached or semi-detached houses with hipped roofs. A hipped roof is a roof where the sides are angled inwards, rather than continuing the existing angle of the walls. Gable End loft conversions involve changing these ‘hips’ to ‘gables’ by adding an extension onto the top corner of the roof so that the walls continue vertically rather than angling inwards.
Mansard Loft Conversion
Mansard loft conversions provide the most space, but often require planning permission because they make extreme changes to the roof. A Mansard conversion involves altering the shape of the roof; rather than having 3 sides making a triangle cross-section, a large projection is created with a back wall that slopes inwards at an angle of 72 degrees. This changes the cross section of the roof to a 4-sided shape.
Double Mansard loft conversions are also an option. Instead of only altering one side of the roof, both sides are extended. This essentially creates a normal, additional storey to the building with slightly angled walls. This is an excellent way to add the maximum possible space to your home. This is not an option for some areas of London due to planning restrictions, but they have been installed throughout Fulham, Clapham, and Wimbledon so speak to our team and architects about your options.
