Overhang
An overhang is a protruding structural element that extends beyond the edge of a building’s exterior walls, most commonly as a projection of the roofline known as an eave or rake. Functionally, it acts as a protective shield for the building envelope by directing rainwater away from the facade and foundation, thereby reducing the risk of moisture infiltration, rot, and soil erosion. Additionally, overhangs serve as a passive climate control feature, providing shade to windows and walls to lower solar heat gain in the summer while often allowing lower-angled winter sun to provide natural warmth. Architecturally, they add depth, shadow lines, and visual character to a structure, ranging from the deep, horizontal eaves of Prairie School design to the minimal, sleek profiles of modern architecture.
