The Urban Farm Masonry Unit (UFMU) is the element invented to bring the farm into the city; to create the hybrid condition implied in the program. It is a masonry unit constructed of a wire mesh exterior skin containing a layer of hay, a layer of dried peat moss, and, in the core, about 80 pounds of soil. The UFMU is intended to use the vertical plane as the growing plane (growing herbs and tuber vegetables), programming the vertical plane of the city as the horizontal plane of the agrarian landscape.
