Rear Dormer

A dormer loft conversion is an extension to the existing roof, creating additional floor space and headroom within the loft conversion. Dormers can be built in various styles, but all extend from the roof slope, usually in a box shape.

The process for building a rear dormer is simpler than most extensions. Many people choose to have a dormer because of the options it can bring. Space is a key reason for having a rear dormer extension. Whether you need a new bedroom or a study if you’re working from home, the possibilities are endless.


Velux loft conversions very rarely require planning permission. Velux are the leading manufacturer of roof windows with over 60 years experience, and A1 are the largest independent client of VELUX products. This type of conversion is generally very cost effective.

A Velux loft conversion requires considerably less construction work than a dormer or other types of conversion. You can add an extra bedroom, living room or office cheaply and quickly – and start enjoying your new conversion within weeks.
