What is Mansard Loft Conversion?

A Mansard loft conversion is characterized by a steeply sloping roof that almost appears vertical to allow for the addition of a full new storey under the roof. This conversion alters the roof structure to create a flat roof with the rear wall sloping inwards at an angle of 72 degrees.

A mansard loft conversion is suitable for urban homes where outward expansion isn’t possible. For example, in tightly packed city areas, a Mansard lets you grow upwards instead of outwards so you can efficiently use your property’s existing footprint.

The construction of a Mansard adjusts the roof structure to create a more upright wall and flat roof. Even though this is one of the more expensive loft conversions, the investment is justified by the substantial increase in living space and property value.

From a practical standpoint, Mansards also integrate large windows or French doors since they enhance natural light and improve the feel of the new level.
