The jettyGlossary Term was a commonly used device by which the timbers of an upper floor project beyond the line of the floor below. The principle could be extended for three- or even four-storey buildings, with each storey stepping forward from the one below. Jetties could be given only to the front of buildings, or to more than one side.
Jetties also provided scope for conspicuous ornament.
In a timber-framed building, the projection of an upper storey beyond the storey below, made by the beams and joists of the lower storey oversailing the wall; on their outer ends is placed the sill of the walling for the storey above.
