Loft Type

Dormer & L-Shaped

A dormer is usually installed to provide more space and headroom within the loft, in addition to improved staircase access.

The dormer conversion is constructed in a way that it projects from the plane of a sloping roof. It is built with vertical walls and a horizontal ceiling, providing a more spacious room for your house.

The installation of a dormer is subject to planning permission requirements from the local authorities only when certain rules aren’t met. Most dormer conversions come under permitted development.

L-Shaped Domers are conversions that uses two dormers, which are built and connected together to form an L shape.

Loft Type

Mansard

This type of conversion is constructed by raising the roof’s sloping side to an almost vertical side.

It is similar to the flat dormer since it has a flat roof, although the windows are housed in a smaller dormer.

The mansard loft extension is a more appealing option to the dormer conversion as it gives the house a better look. The challenge to this type of loft conversion is that it requires planning permission due to the enormous changes to the shape and structure of the house.

This loft conversion is a common choice as it maximizes space to create an additional room with the loft built at the rear end of the house with a flat roof and back wall sloping at a 72-degree angle, and windows housed in small dormers that extend from the roof.

Add Value To Your Property

Recent studies show that a loft conversion that added a double bedroom and bathroom to a three-bed, one-bathroom house can add about 20 per cent to its value.

Loft Type

Hip-to-Gable

The hip-to-gable loft conversion has become a popular choice as the spaces have small internal volume.

It is the most innovative way to maximize small spaces. This conversion requires planning permission as it means structural alterations to the roof.

The size of the room is increased and allows for more headroom by extending the roof’s ridgeline from its existing hips to the end of the vertical wall and altering the side of the house that’s into a flat end gable.

Loft Type

Velux

This type of loft conversion is desirable if your roof has plenty of available headroom. The cost of a Velux loft conversion is likely to be lower and the build time is generally less.
