Mansard

What is a Mansard Conversion?

A Mansard Loft Conversion is named after the 17th Century French Architect Francois Mansard. A Mansard is usually located at the rear of the property. However, in some circumstances a Mansard could be located at the front. This will depend on the type of house and if other properties near by have already had this design completed and permission granted by your Local Council. A Mansard Conversion has a Flat roof with a slight fall to allow water to run into the gutter and the face of the Mansard slopes back 72 degrees which creates that distinctive Mansard design.

Benefits of a Mansard Conversion

Mansard loft conversions are a perfect way to gain more usable space out of your Loft or Attic. If you’ve decided to have a Loft Conversion, chances are you may want another bedroom, bathroom, playroom, lounge or office. A Mansard Conversion can add that extra living area in the form of a stylish and practical addition.

In certain areas of London and the Home Counties this design is most favoured with Planning Officers rather than constructing a Rear Dormer Conversion.

Exterior finish options

The exterior finish of your Mansard Conversion can either be brick, tile or slate hung. The tile or slate will be chosen on site so that they match the existing roof as close as possible. If the client decides on brick, the brick used will be matched to the existing brickwork. Other external finishes that will be matched to the existing as close as possible will be Fascia, Soffits, Gutters and Windows. This way the Mansard Conversion will look like it was always part of the original property.

Will you need planning permission?

If your property has Permitted Development Rights, as long as you adhere to the councils guidelines, a Mansard Conversion can be built under a Certificate Of Lawfulness. A Certificate Of Lawfulness means as long as you build within the guidelines you do not need to wait for the application to be approved before work commences.

If you do not have Permitted Development Rights you will need to obtain Planning Permission. With Planning Permission you can not start work until Planning Permission has been granted. Once a Planning Application is valid with the council they should issue a decision after 8 weeks.

Here at The Loft Room we will ascertain exactly which permission is needed and we will submit the relevant application to obtain the correct approval on your behalf.
