The majority of Glasgow's tenements were built between 1880 and 1914, with red, beige, and grey sandstone from Stranraer and Dumfriesshire quarries. The tenements were one-and-two-up-and-down-stairs houses with front doors but no landings or internal doors leading from one room to another. There was usually a backyard shared by several houses with a communal area behind them called a "green." Each house had two rooms upstairs and three downstairs, for a total of five rooms. There was also a kitchen at the back, which may have had its own door onto the green or may have been accessible only through a door into the backyard. A privy sat next to the back door of each house. Glasgow's streets were not designed for automobiles; there were no parking laws and no street signs. Most drivers just parked where they could, which often meant pulling up alongside the curb. This made it difficult for people to get in and out of their cars, so motor vehicles were a rare sight in town until very recently. The city's wide avenues were originally royal hunting grounds used by kings such as Robert the Bruce and William Wallace to chase deer and other game. They were also where nobles displayed their wealth by planting large gardens filled with trees and statues.
