I know an architect who aspires to be the Ernest Hemingway of architecture; using simple materials, effectively. Here’s an outdoor garden solution of which she would approve.
When Brazilian architect,Philip Scroback built his reinforced concrete house in Sao Paulo (see "A High Style Solution"), he extended the feel of the concrete floor into his urban garden by placing large stone pavers on a bed of gray gravel. The materials for this elegant solution are easy to find and economical; a perfect Hemingway solution.
