Door head column designs typically involve architectural elements used to support the roof or ceiling of a building's entrance. These designs can vary greatly in style, material, and decorative elements, reflecting the cultural or historical context of the building. They are often crafted from materials like wood, stone, or metal and can be embellished with carvings or other artistic features. In architectural design, the columns serve not only a structural purpose but also an aesthetic one, contributing to the overall look and feel of the building.
