In the design of a fence along existing property lines, a connection was derived from the contemporary form of the residence, in particular, the materials used in the construction.  Oxidized steel and Massaranduba wood created a matrix, allowing a sense of slight visual privacy, but ensuring territoriality.  Twenty foot sections of the matrix were linked to conform to the natural topography.  Three foot gates that worked with the wood and steel patterns permitted access into the yard.  Over time, the characteristics of the two materials replaced each other; wood, normally thought of as a warm material, grayed with sun exposure, while steel, a cold material began to take on a warm, rusted patina.  A total of 135 linear feet of custom fencing was designed and installed.
