Metal shingles cut from scraps of sheet metal mix with new material as well as odds and ends, such as a road sign Baker bought at the Alameda Flea market. Baker designed stainless steel clips that allow any tile to be easily moved or replaced without the use of tools. Planter box panels add functionality to the facade and can be swapped out or relocated throughout the year.
