In towns, which expanded greatly during the period, landowners turned into property developers, and rows of identical terraced houses became the norm. Even the wealthy were persuaded to live in these in town, especially if provided with a square of garden in front of the house. There was an enormous amount of building in the period, all over the English-speaking world, and the standards of construction were generally high. Where they have not been demolished, large numbers of Georgian buildings have survived two centuries or more, and they still form large parts of the core of cities such as London, Edinburgh, Dublin and Bristol.
