#9  Liberty Street, residential block and highway ramp          Recycling
The house is enclosed on the north by the embankment of the roadway with the lowest level set into the hillside.  The south-facing building skin is grey metal; it provides an outer layer of protection separate from the internal construction.  Other boundaries are made by plants.  The space within is constructed of earthen materials and steel.  In the house, production and loss are nearly identical with one another; they often exchange places.  Productive aspects of the residence are centrally located, and leisure activities occur at the periphery; production and leisure intersect at places of maximum external exposure.  Separation between the occupants is made by the orientations of surfaces:  the house has no rooms.  Views from within are directed upward to the sky and south to the city below.  The ceiling is gridded in the form of a calendar but does not contain specific dates; a scale is suspended from the calendar.  The house is leasable by two people from the city for a period of nine months.
