Mansard loft conversions are an excellent way to get more usable space out of a loft or attic, providing more headroom than any other type of conversion.

If you’ve decided to have a loft conversion, chances are you may want another bedroom, bathroom, playroom, lounge or office. The Mansard roof can add that extra roof area without the use of more masonry, in the form of a stylish and practical addition.

Here are some of the benefits of a Mansard loft conversion.

• As Mansard lofts have dormer windows, this is a great way to get more light into your new loft living space.
• They don’t require much in the way of structural reinforcements.
• The straight walls make them easier to furnish than lofts with slanted roots.
• Mansard lofts are very versatile.

What is a Mansard roof?

Named after the 17th Century French architect, Francois Mansart, this particular architectural style involves using the entire plane of a property’s roof, and extending the slope out vertically (typically 72-90 degrees) to create more living space.

The Mansard roof (also known as a French roof), helped Mansart make a name for himself, and is a four-sided, double sloped gambrel roof with windows on the lower slope. The earliest known example of a Mansard roof can be found on a section of the Louvre museum in Paris, dating back to 1550.

What’s involved in a Mansard loft conversion?

A Mansard loft conversion involves opening up your roof to have three sides instead of two. These major changes to the pitch of the roof may require a great deal of exterior work.

So plan for extra construction, compared to a basic conversion, and decide whether you’re prepared for the additional time and expense that it may require.

Mansard loft conversions are suitable for most types of property including terraced houses, bungalows, detached and semi-detached houses. However they are more commonly seen in urban areas like London on rows of older terraced houses, as opposed to suburban areas. The walls of the mansard loft can look however you want them to, whether you prefer slate tiles, exposed brick, or just a normal wall.

What are the possible downsides to a Mansard loft conversion?

• Mansard loft conversions involve extending your roof space, and so planning permission is almost always required. Therefore it is worth finding out what the attitude is of your local council to these types of extensions. Be sure to leave extra time within your project to obtain the necessary documentation.
• Mansard roof conversions generally cost more than a hip-to-gable or dormer conversion, so you should obtain detailed quotes to budget for the work.
