A dormer (window) 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. Internally, a dormer will have a horizontal ceiling and vertical walls compared to the normal diagonal sides of a conversion. In lofts that have limited space or headroom a dormer will provide additional space that can make a conversion feasible.
Flat roof dormers tend to give the maximum amount of additional internal space although they do not look as attractive from outside the property. Gable fronted and hipped roof dormers look much more attractive but they often do not give as much internal space and will cost more to build due the extra complexity.
Different types of dormer loft conversions:
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.
Mansards are commonly built by raising the party/gable walls either side of your house to make the profile for the mansard and then creating the timber frame. Although common on older properties, especially in cities like London, Mansards are not often seen in the suburbs. Flat roof dormers tend to be a more popular choice for the ‘average’ 3 bed semi or terrace house due to the reduced cost and simpler construction. A mansard loft conversion will almost certainly require planning permission. Things to consider.
While this type of roof will give you the maximum amount of space in your loft conversion it does a downside. As it involves replacing the entire roof the constructions costs will be high. Therefore, it is quite unusual to see this type of conversion, unless the orignal roof was built in this style.
Different types of mansard loft conversions:
Hip to gable loft conversions increase the small existing loft space of properties with sloping or hipped roofs by modifying the hipped (sloping) side of the loft to form a flat gable end.
The majority of properties in London have a hipped (sloping) roof, which usually means a small loft space. With the existing loft space so small if often makes a loft conversion difficult. Hip to Gable loft conversions solve this problem by maximising the amount of availble loft space & making it possible to use the space for additional living areas.
To make the very most of the loft space, some properties can have a double hip to gable loft extension, which converts both sides of the properties hipped roof into gable flat ends providing ample room for a large new living space.
An L shape mansard conversion can be achieved on Victorian / Edwardian houses & flats where a rear addition / outrigger is present to the back of the property allowing the mansard to extend over this area. The additional space over the back can be used as an extra bedroom, a study, a separate bathroom, a nursery or simply an even bigger en-suite or separate dressing room.
L shape mansards are a great use of space and will help increase the value of your property. See our gallery page for photos of these types of projects.
L shape Dormers are very similar to a rear dormer conversion (90 degrees angled wall) but with an additional room over the rear addition / outrigger.
