Glasgow and Edinburgh
Tenements make up a large percentage of the housing stock of Glasgow and Edinburgh in Scotland. Glasgow tenements were built to provide high-density housing for the large number of people immigrating to the city in the 19th and early 20th century as a result of the Industrial Revolution, when the city's population boomed to more than 1 million people. Edinburgh's tenements are much older, dating from the 17th century onwards, and some were up to 15 stories high when first built, which made them among the tallest houses in the world at that time. Glasgow tenements were generally built no taller than the width of the street on which they were located; therefore, most are about 3–5 storeys high. Virtually all Glasgow tenements were constructed using red or blonde sandstone, which has become distinctive.
