Architecture of Scotland in the Industrial Revolution includes all building in Scotland between the mid-eighteenth century and the end of the nineteenth century. During this period, the country underwent an economic and social transformation as a result of industrialisation, which was reflected in new architectural forms, techniques and scale of building. In the second half of the eighteenth century, Edinburgh was the focus of a classically inspired building boom that reflected the growing wealth and confidence of the capital. Housing often took the form of horizontally divided tenement flats. Some of the leading European architects during this period were Scottish, including Robert Adam and William Chambers.
