Jettying
open-in-new
<p>Jettying (jetty, jutty, from <a href="/facts/Old_French/QcRpPdAc">Old French</a> <i>getee, jette</i>) is a building technique used in <a href="/facts/Medieval/RqzEKB9v">medieval</a> <a href="/facts/Timber_framing/XN7NyKbo">timber-frame</a> buildings in which an upper floor projects beyond the dimensions of the floor below. This has the advantage of increasing the available space in the building without obstructing the street. Jettied floors are also termed <i>jetties</i>. In the U.S., the most common surviving <a href="/facts/American_colonial_architecture/KLWJe6NU">colonial version</a> of this is the <a href="/facts/Garrison_(architecture)/jUksqDx6">garrison</a> house. Most jetties are external, but some early medieval houses were built with internal jetties. </p>
