Types of Loft Conversion

When it comes to a loft conversion, there are lots of different options to consider. Every home is different and unique, which is why one type of attic conversion does not suit all. There are six main loft extension types and the type relevant to your property will depend on the style of your property, roof height, available space, planning regulations and budget.


Rear Dormer

A rear dormer is the most popular loft conversion.

The back slope of the existing roof is removed and built up vertically from the rear elevation.

Rear dormer roofs are flat roofs with a slight slope on the external layer of the roof to allow for rainwater to run off into its gutter, whilst the dormers internal ceilings remain completely level.


A Velux conversion is a type of loft conversion where the roofline is unaltered.

A Velux conversion is the most non-intrusive, cost-effective and easiest way to create additional space.

Only official branded Velux windows are used on our conversions as they are the leading manufacturer in the UK and the windows come with their own product guarantee.

We tend to recommend Velux windows in the front pitched roof of our dormer loft conversions to allow additional light into the loft.

Hip to Gable

A hip to gable conversion is a popular option for detached or semi-detached properties with a hip sloped roof. The new loft is built from the bottom of the side slope up vertically and extend the existing ridge to create a gable end.

A hip to gable loft conversions can also be combined with rear dormer and L-shaped loft conversions.

A hip to gable is not suitable for mid-terraced homes.


L Shaped Dormer

L-shaped dormer is part built over the main part of the roof and part built over the rear part of the roof, which then creates the distinctive L-shape from a bird’s eye view. L-shaped dormers are normally only suitable where there is an existing two storey back addition to the rear of the property.

L-shaped dormer loft conversions are the best way to extend mid-terrace properties.

Pitched Dormer

A pitched roof dormer loft conversion is a popular choice when the height of the existing roof is sufficient enough to accommodate one. This type of loft conversion is usually regarded as one of the most aesthetically pleasing designs with an extraordinary amount of character.

Side Dormer

This form of loft conversion is normally the same shape as a rear dormer conversion but is situated on the side of the property. The side existing slope is removed and built up vertically from the rear elevation

If the property is detached, you can sometimes maximise the space even more by constructing a side dormer on both sides of the roof (as per the photo above).
