Boulder A.D.U. / Tres Birds
One of the newest housing trends in American backyards is the A.D.U. or Accessory Dwelling Unit. An A.D.U. is a small house located on the same lot as a single-family home. It’s an independent residential unit that can be a guest house, a home for extended family, or even an office or a party space.
