At SkyLofts we know that there are many various terms related to loft conversions that you may not be familiar with. We’ve pulled all these together to form a loft conversion glossary of the common terms with an easy to understand explanation that will make you feel more comfortable when speaking with your loft conversion builder.
1. Loft Conversion
A Loft Conversion involves building an additional room/s such as a bedroom and a bathroom in the loft space of your home. If you are looking to increase the living space in your home without eating into your garden with an extension then a loft conversion is a cost-effective way to achieve this.
If space and headroom within your loft are limited, it may make sense to opt for a dormer style conversion. A dormer is where the roof is extended to give more internal room to the conversion, you can read all about dormers here.
A mansard conversion where the roof is converted to have two pitches on each side, you can read all about mansard loft conversions here.

A hip to gable loft is where you change the sloping side of your property (the hip side) to a flat gable end to create a much larger loft space, you can read all about hip to gable loft conversions here.
