Which loft conversion is right for your home? Here we explain the differences between each of the loft conversion types.

There are four main types of loft conversions:

Dormer Loft Conversion:

A dormer loft conversion is an extension of the existing roof; it projects vertically from a sloping roof. This generates additional floor space and headroom within the building.

There are four types of dormer loft conversions: Flat Roof Dormer, Gable Fronted Dormer, Hipped Roof Dormer, Shed Dormer

The most common option for a loft conversion is the flat roof dormer due to it being the most cost effective and offering the most additional internal space. The gable fronted dormer is more attractive and consists of a gable wall extension, built up to the existing ridge line with a roof section built outwards to the new gable end. A hipped roof dormer is similar to the gable, with three sloping planes of a hipped roof converging at the ridge of the dormer. The shed dormer is comparable to the flat roof dormer but slopes downwards at an angle shallower than the main roof.

Velux Loft Conversion:

To convert your loft in the most cost effective way would be a Velux loft conversion as no external alterations are required. The roof line remains untouched, as the Velux windows are installed flush which leaves the original roof structure unaffected.

Mansard Loft Conversion:

A mansard loft conversion is installed to the rear of a property, it has a flat roof and a back wall that slopes inwards at an angle of 72 degrees. Windows of this type of conversion are usually housed within small dormers.

Hip to Gable Loft Conversion:

A hip to gable loft conversion extends your property on the sloping side and as such is a popular choice for owners of semi-detached properties, replacing the sloping roof with a vertical wall (the gable) at the end to the same height as the ridge and filling space in between. If your property has two sloping roofs, both could be replaced with vertical walls. This would implement a double hip to gable loft, creating even more space.

Expert Tip – Loft Windows

“The most common solution is to follow the existing pitch line of the roof and install a rooflight. The rooflight is fitted by removing the tiles and battens where the window will be placed. The rafters are cut to fit the unit, and the others reinforced to take its weight. The frame is then fitted and flashings are installed before finishing off the surrounding tiling.”

Expert Tip – Loft Storage

“If your loft was previously used just for storage, you need to consider where you’re going to put everything once the space is converted. To make the most of your new space bespoke cupboards built to fit the space available are a great solution – making sure to use the wasted space beneath the sloping eaves at the sides of the converted space.”
