Types of Loft Conversions: Which style will suit our property?

Has your family found themselves getting in each others way? Are the kids growing up and demanding their own bedroom? Another option to moving house would be to convert your loft space. It will not only save you from all the stress and costs of moving house but will give you the extra room you may need, in turn adding more value to your property too!

There are three main types of loft conversion. Which one you will choose which will depend on your needs, location and situation. The three types are the Mansard, Dormer or Velux.

The Mansard is more commonly used in city/ town centres. This is due to the fact the Mansard requires minimal alterations to the outside of the property so you can maximise the amount of space from your property with the minimal amount of disruption to you and your neighbours while the conversion is in progress.

The Dormer is mostly used in the smaller property or where the loft may be a little small to house a conversion. Dormers provide extra headroom and also space for a staircase which is highly beneficial to those smaller properties.

The Velux is mainly used in listed buildings or buildings in a designated area – an area of natural beauty. The Velux is used in these buildings as the conversion is created in the existing loft space. The “Velux” windows are fitted in line with the existing roof to keep the aesthetics unchanged.

Careful consideration should be taken when choosing the style of conversion for your property to ensure it suits both you and your house! If you require any advice dont hesitate to contact us as we have a team of highly experienced staff to offer advise.

The Mansard

A Mansard roof has 2 slopes. The lower of the 2 slopes is close to vertical at 72 degrees and the top of the roof is almost horizontal. The Mansard roof has the advantage of maximising the available space in your loft.


Velux windows & rooflights are the same.  Charles Grosvenor only fit Velux windows, we never use the cheaper brands that are around.  A roof window conversion generally needs no planning permission & are very cost effective.


A dormer conversion is an extension to your existing roof.  This allows for additional floor space & headroom within the conversion.  A Dormer will protrude from the roof slope & are normally built at the rear of your property.  If your loft has limited space & headroom then a dormer will provide the extra space to make a conversion feasible.

Hip to Gable

A hip to gable conversion will involve some major changes to your roof.  The gable wall is built up to the ridge line & a new section of roof is built to fill in the gap.  Generally houses with a hipped roof will not have enough internal volume so a hip to gable conversion will be the best solution.
