This type of conversion is generally designed within the inner London areas, where clients are following the Mansard trend of similar conversions within their locality.

Construction

A mansard is constructed by raising the party walls either side of your property in brick and then creating a timber frame between the two new walls. The rear face of the mansard should slope backwards at 72degrees to comply with planning requirements.
