An attic is a space located directly under the roof of a building, often used for storage. It can be accessed by a staircase, ladder, or pull-down stairs. Attics are typically unfinished, meaning they may have exposed beams and insulation, but some are converted into living spaces, such as bedrooms or offices. Attics can vary in size and shape, depending on the design of the building. They often contain items that are not frequently used, such as seasonal decorations or old furniture. Proper ventilation and insulation are important in attics to prevent moisture buildup and maintain energy efficiency in the home.
