What is a facade? A facade is the front or face of a building, often the most decorative and visually striking part. It serves both aesthetic and functional purposes, acting as a barrier against weather while showcasing architectural style. Facades can be made from various materials like brick, glass, stone, or metal. They often feature intricate designs, windows, and doors that add to the building's character. In modern architecture, facades can also include advanced technologies like solar panels or smart glass. Understanding facades helps appreciate the artistry and engineering behind building design.
