A dormer is a small structure with a roof, that projects outwards from the main roof. They usually have dormer windows set into them. Some of the reasons dormers are so popular, is that they create extra headroom without having to add another storey. This makes them especially popular with bungalows. It’s much more cost effective to add on a dormer with a window, compared to adding another storey.

A Dormer conversion is one of the more common types of loft conversion within the UK and is mostly used on semi-detached or terraced houses. These conversions extend the roof upwards to create more headspace, changing quite a lot about the size and shape of your roof in the process.

Dormer designs are very simple, but they can sometimes have limits to how far they can be extended. Changing too much can heavily alter the silhouette of your home, so they always require planning permission and often have to be kept simple to stay consistent with the rest of your home.
