Traditionally, jettying was the art of creating overhangs and is seen mainly in timber-framed houses of the 14th – 17th centuries. The jetty (derr. French ‘jeter’ to throw) was where the upper floor overhangs the floor below by as much as 1,200mm although usually around 400mm was more normal. If a house comprised two storeys above ground, the second storey would often overhang by as much as the one below.

A jetty would often exist on the front of the house where it was most visible, although some houses show them on both front and back.

= Reasons to jetty =

Although the exact reason for jettying is not known, the most common cited is the need to provide extra space. While this is plausible – especially in the confined conditions of a medieval town – many of these buildings were in rural areas which did not have the same constraints. In any case, the space provided by a modest jetty may not have yielded significant usable space.

More likely reasons are:

* Fashion: If jettying originally started in towns, rural builders may simply have been keen to be seen ‘keeping up with the times’ and offering the latest building techniques.
* Structural 1: A heavy item of furniture in the middle of an upper floor room could, over time, cause sagging of the floor joists. By placing such heavy items in or close to the jetty – and therefore directly above or closer to the point where the joists bear on the wall below – much of the weight of the item is directed to the wall below and could also straddle over the wall.
* Structural 2: In a house with a two-storey central hall, jettying would require timbers only one-storey high, as opposed to timbers that extended right up to the eaves.
* Social status: Jettying was an added expense to the cost of building so having a jetty may have been a way of expressing the wealth of the householder.

Weathering: These buildings seldom had eaves gutters and down pipes so much of the water running-off the roof would flow down the walls. The inclusion of a jetty may simply have been a precaution against damp, protecting the lower floor from the run-off.

The term ‘jetty’ is rarely used in modern building; ‘overhang’, ‘projection’ and ‘cantilever’ are more common.
