A Velux loft conversion is where a loft space is converted into one or more rooms using Velux windows.

With a Velux loft conversion, the existing loft space is converted without changing the structure of the roof, thus preventing the need for planning permission. If you wish to keep your existing roof, there needs to be adequate headroom for this type of conversion to work. With the Velux windows you also let the daylight and create extra light into your loft conversion.
