Benjamin Hall Design uses masonry walls for Arizona accessory dwelling unit

Local studio Benjamin Hall Design has attached an accessory dwelling unit made of concrete block to an existing house to accommodate a multi-generational family in Phoenix, Arizona, USA.

Known as Moon Valley Residence, the 1,756-square-foot (163-square-metre) dwelling was designed to intentionally contrast the original 1970s suburban main home, set in a golf community that looks eastward to a rock formation called Lookout Mountain.
