What is a Mansard Loft Conversion?

A Mansard conversion typically alters the rear of a property, giving it a horizontal roof with a nearly vertical back wall slanted at 72 degrees. This setup not only provides vast interior space but also allows natural light to flood in through dormer-style windows. These conversions blend seamlessly with the original design of the house, giving the impression that the addition has always been part of the property. The aesthetic appeal paired with functionality makes this a desirable option for homeowners.
