We convert the loft area you already have by putting in windows sloping with the roof. Velux is the most established and popular company that makes a flat fitting window which can open by sliding or an angled opening. The windows are added for light without the need for creating more substantial roof alterations, they can be used to convert loft space above the house to a living space or just a well lit storage space adding value to your property price. You can use Velux windows to create a dormer loft adding extra space and headroom and more natural light to the room-space. The roof area and the floor or the loft room are supported or opened, we sometimes raise or change the shape of the roof to be more like a terraced attic area.
