Mansard Loft Conversions

Similar in construction and design to dormer loft conversions (i.e. flat roofs and a prominent window feature), mansard loft conversions are created by raising the height of the party walls on either side of a property.

Although they are subject to stricter planning regulations than dormers, mansard loft conversions are still very popular as evidenced by their numbers in built-up urban areas such as London and, to a lesser extent, Cardiff.

Other reasons why our clients like this style of conversion include:

  • Mansard loft conversions, in effect, add an extra storey to your property thus providing maximum space – more than any other type of conversion
  • Highly adaptable – suitable for almost any type of property, especially terraced houses
  • With regards to aesthetic, mansard loft conversions can easily be finished to match the existing exterior design of a property.

Despite stricter planning restrictions, Mansard loft conversions are an attractive option for anyone looking to maximise living space and add value to a property.
