What is a Mansard Loft Conversion?

Mansard conversions are usually built on the rear of the property. They have a horizontal roof and an almost vertical back wall at 72 degrees. The conversion has an immense amount of room and room-sized proportions. Windows are often included and installed within a box-shaped Dormer. These windows allow lots of natural light to flow in. As the windows are facing outwards they make the mansard conversion look as if it has always belonged to the house.

The different types of Mansard Loft Conversions

Different types of Mansard Loft conversions can be performed.

  • L-shaped Mansard – This creates even more space than a rear Mansard as a further room is added to the back of the home, usually above the kitchen.
  • Double Mansard – The largest loft conversion available, a double Mansard comprises a front and rear Mansard, essentially creating an entirely new storey. Double Mansards are particularly suited to period London homes.

Mansards can also be carried out on listed buildings and properties located in London conservation areas as long as they are built to local authority planning permission and regulation guidelines.

What are the benefits of a Mansard loft conversion?

If you are adding a mansard loft conversion to a terraced or semi-detached property. Then your neighbours have to be informed and agree with the work you are proposing to carry out. This is because work will likely be carried out on the party wall that you share with your neighbours.
