The area directly below the roof line where windows are found is called the "dormer." Dormers are structural elements that project from the slope of a roof, allowing for natural light and ventilation in the space below. They can enhance the aesthetic appeal of a building while providing additional usable space in attics or upper floors.
Velux roof windows are widely available from building supplies companies. For example Velux windows can be bought from Screwfix, Wickes and Ken's Yard.
