Mansard & Pocket Dormer


Mansard & Pocket Dormer

Mansard & Pocket Dormer - Amongst the alternatives to a large Box Dormer is to have a few small Pocket Dormers instead (as shown on the house on the left below). These mini Dormers also help to create extra usable space inside the Loft although not as much as a large Box Dormer would. This is because there is a remaining section of pitched roof between the Pocket Dormers, and either side of them, which cuts into the Loft space. To mitigate this effect you might, depending on the style of house, be able to set the Pocket Dormers inside a Mansard Roof (like the house below on the right). This involves building up the Party Walls at either side of the property (in pink) and building a much steeper pitched roof (in violet) to improve the space in the loft. Pocket Dormers can have either flat roofs or pitched roofs.
