"To facilitate increased residential density within the city limits of Portland, Oregon, home owners can add &amp;quot;detached accessory structures&amp;quot; to their residential lots under a housing ordinance provision for &amp;#8216;co-housing.&amp;#8217;  One example, the Garden Cottages at Ruth&amp;#8217;s House are two tiny homes adjacent to a larger dwelling. The bathroom uses a combo sink and toilet fixture to save space and water. A large deck acts to expand the living space to the outdoors.  Eli Spevak of Orange Splot Cohousing Development of Portland, constructed the two &amp;quot;detached accessory structures&amp;quot; on a single-family residential lot next to a existing home. The cottages were part of the &amp;lt;i&amp;gt;2009 Build it Green!&amp;lt;/i&amp;gt; home tour."^^<http://www.w3.org/2001/XMLSchema#string>
