What is a Mansard Loft Conversion?

Are you thinking about increasing the size of your property? If so, then you may be wondering what is a Mansard loft conversion is.

Mansard loft conversions is where a loft roof is modified so that the sloping part of the roof is almost flat (between 72 – 90 degrees), and the sloping front wall being almost vertical.  Because of this gradient, windows are built in the new roof as small dormers.

These types of conversions create the feeling of an extra storey rather than the usual loft conversion look.  Loft conversions are a great investment as they add space and value to your home.  You can get a rough idea of loft conversion costs here.
