Which Loft Conversion Type to Choose?

You may well be looking to convert your loft to create an extra room in your house. And whether it’s for a new bedroom, bathroom, office, play area or any other number of reasons you will still need to decide which type of loft conversion is best for you.

Well to make things relatively easy there are 4 main types of loft styles to consider:

  • Velux
  • Dormer
  • Mansard
  • Hip to Gable

Velux Loft Conversions: This type of conversion is named after the main manufacturer of the velux-loft-conversiontype of roof window that is normally fitted.

The conversion itself is the most straightforward of all the conversion types as it doesn’t require planning permission. This is due to the fact that the windows are normally fitted flush to the roofline and none of the main structural support of the roof is altered in any way.

Given that it only requires additional windows to be fitted this is one of the least expensive loft conversions available.

Dormer Loft Conversions: This type of conversion, one of the most popular, involves a lot of work loft-conversion-optionsas it is an extension to the existing roof structure. It creates a great deal more extra space in the loft as it extends up vertically from the existing roofline.

Due to the construction nature of a Dormer conversion/extension it is a lot more expensive than a Velux conversion. And even though it is a substantial conversion in some cases you may not need to get planning permission. Although if you plan to carry out this type of conversion yourself you should seek professional advice on planning matters.

You also have a number of Dormer types from which to choose:

  • Flat roof dormer
  • Gable fronted dormer
  • Hipped roof dormer
  • Shed dormer

Hip to Gable Loft Conversions: This type of conversion, which is more likely to need planning permission, hip-to-gableis created by converting the sloping end of your property, also known as the ‘hipped end’, into a vertical/flat area.

The additional space provided by this conversion type is not that substantial so coupled with the fact that it’s highly likely you will need planning permission does not always make this a first choice loft conversion option for many homeowners.


Mansard Loft Conversions: This conversion type, named after a 17th century French architect Francois Mansard, is mansard-loft-conversioncompleted on the roofline to the rear of the property.

The conversion has a flat roof, where the back wall slopes inwards at an angle of 72 degrees. And small dormers normally house the windows.

And due to the substantial nature of changes to the roofline it’s almost certain planning permission will be required.
