Overhang
Definition and meaning of Overhang in real estate.
An overhang is a projecting portion of a roof, upper story, or architectural feature that extends beyond the exterior vertical wall of a building.
In more detail
Overhangs serve both functional and aesthetic purposes in building design. Roof overhangs protect the exterior walls, windows, and foundation from rain and snow, reducing water infiltration and structural wear. In passive solar design, calculated overhangs block the high summer sun to keep the interior cool while allowing the lower winter sun to heat the home. They are also common features in various home styles, providing architectural character and shadow lines.
