In America and other colonies wood remained very common, as its availability and cost-ratio with the other materials was more favourable.
Raked roofs were mostly covered in earthenware tiles until Richard Pennant, 1st Baron Penrhyn led the development of the slate industry in Wales from the 1760s, which by the end of the century had become the usual material.
The style was revived in the late 19th century in the United States as Colonial Revival architecture and in the early 20th century in Great Britain as Neo-Georgian architecture; in both it is also called Georgian Revival architecture.
In the United States the term "Georgian" is generally used to describe all buildings from the period, regardless of style; in Britain it is generally restricted to buildings that are "architectural in intention", and have stylistic characteristics that are typical of the period, though that covers a wide range.
Greek Revival architecture was added to the repertory, beginning around 1750, but increasing in popularity after 1800.
Versions of revived Palladian architecture dominated English country house architecture.
Houses were increasingly placed in grand landscaped settings, and large houses were generally made wide and relatively shallow, largely to look more impressive from a distance.
The period brought the vocabulary of classical architecture to smaller and more modest buildings than had been the case before, replacing English vernacular architecture (or becoming the new vernacular style) for almost all new middle-class homes and public buildings by the end of the period.
Georgian architecture is characterized by its proportion and balance; simple mathematical ratios were used to determine the height of a window in relation to its width or the shape of a room as a double cube.
