A "floor" is the lower surface of a room or building that people walk on. It can be made from various materials, including wood, tile, carpet, or concrete. Floors provide stability and support for furniture and other objects placed on them. In architecture, the term "floor" can also refer to different levels within a structure, such as the first floor, second floor, and so on. Each level may have its own unique design and purpose, contributing to the overall layout of the building. Floors are essential for both functionality and aesthetics in spaces like homes and offices.
