Flushwork

In architecture, flushwork is the decorative combination on the same flat plane of flint and ashlar stone. If the stone projects from a flat flint wall then the term is proudwork, as the stone stands "proud" rather than being "flush" with the wall.

Flushworked buildings belong to the Perpendicular style of English Gothic architecture. It is characteristic of the external walls of medieval buildings – most of the survivors being churches – in parts of Southern England and especially East Anglia. Flushwork begins in the early 14th century, but the peak period was during the wool boom between about 1450 and the English Reformation of the 1520s, when church building virtually ceased and brick construction became more fashionable. The technique continued in occasional use, and saw a major revival in the 19th century, and is still sometimes used in a modern style today, as well as for the restoration or extension of older buildings.
