Mansard Loft Conversion

A mansard loft 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.

Mansards loft conversions 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.

This type of loft conversion is generally designed within the countryside areas of the North West, where clients are following the Mansard Loft trend of similar conversions within their locality. This type of conversion was the preferred design a number of years ago, and would most likely be the preferred option from a planning perspective in sensitive areas.
