👉 Underhanging is a term used in structural engineering and construction. It refers to a portion of a structure that is suspended or supported by other structures, often by beams or cables, without having a complete roof over it. This concept arises when a building or structure has openings such as windows or doors, which are not fully covered by the walls or floors. Underhanging can be used to improve structural stability and provide additional space for ventilation or heating systems.
