During the early 18th century Georgian period in England, interior design evolved from the Baroque style. Interiors became lighter and featured new woods like mahogany. Furniture accumulated in rooms for decorative purposes, including bookshelves, porcelain collections, and busts from the Grand Tour. Wallpapers became popular in bedrooms while paneling remained in other rooms. To house the growing middle class, architects developed terraced housing and town squares that brought nature into cities through lawns, trees and flowers. Interior architectural details like plasterwork and broken pediments became more ornate.
