One of the most common types of loft conversions at S and C joiners is the dormer. It is usually built out of the existing slope of the roof and provides a cost effective way to add extra space to your property. Some types of dormer loft conversions can result in up to 50 cubic metres of additional space, this depending on the type of house, size and style of the extension. In addition, much of the work involved can be carried out from scaffolding outside your home, making for minimal disruption when compared with most other types of home extension.
There are several different types of dormer loft conversion and the one most suited to your property will depend on your type of house (terraced, semi-detached, detached) and your existing roof shape.
The flat roof dormer is a structure that can be added to the front and/or rear of the loft. It provides a fairly simple way to expand the usable space in the loft, increasing head height and providing lots of natural light afforded by the dormer windows.
The shed roof dormer is similar to the flat roof option but its roof slopes down at an angle slightly, it can be constructed with different materials and is usually more suited to homes with a gable roof.
The gable fronted dormer, which is sometimes also known as a dog-house dormer is a more complex solution consisting of a gable wall extension which is built upwards to meet the current ridge line, with a new sloping roof section also built towards the new gable end.
A hipped roof dormer is an extension where the roofs slope on all three sides of the structure, often an aesthetically pleasing look especially suited to properties in some styles, but this type of dormer construction results in less usable space in the new loft than for example, a flat roof dormer.
