A house is a building which serves as a home. Houses are traditionally constructed using materials such as wood, stone, cement, steel, or brick. They come in different sizes, shapes and designs, from the most basic of homes to the most luxurious and complex. They may include buildings for family, office, leisure and entertainment, as well as spaces for gardening and other outdoor activities. Houses range from single-family dwellings to multi-story, multi-unit dwellings such as apartment complexes, dormitories, or condominiums. Houses may also include garages, workshops and other accessory structures.
