What is dormer loft conversion?

The dormer loft conversion is actually a structure that is an extension and protrudes out of the original sloping roof under which additional space can be created with extra headroom. Using this type of conversion, even the smallest of loft rooms can be made larger with dormer windows transforming the space by adding light. This type of conversion can be carried out at the back or at the front of a loft and is probably the simplest way of providing extra space in a home.

A loft conversion that is called a shed-roof-dormer is a very similar way of extending space as is often done with the flat roofing option but in this option will be angled the roof slopes at and can be constructed using various materials.
