A beach house is a house on or near a beach, generally used as a vacation or second home for people who commute to the house on weekends or during vacation periods. Beach houses are often associated with beach gardens with a special planting and a particular type of leisure use. The exteriors may have lap siding with standing seam metal roofs reflecting a true cottage style or they may be stucco clad with barrel tile roofs indicative of a Mediterranean villa, either completely at home in a coastal resort environment. Many beach style house plans feature elevated living spaces over an island style basement that is fitted to coastal site conditions where flooding is a concern. These lower spaces may feature parking, storage and unfinished areas that can be converted into such uses as game rooms, exercise rooms, or flex rooms that can accommodate visiting grandchildren (conditional upon site zoning requirements).
