Cohouse is a single dwelling, with floor plan designed to enable by simple closure of some doors the creation of several large, acoustically and visually isolated studio townhouses. These units may be further partitioned into separate rooms by cabinetry. No building work or permits are required. Each unit has a private garage, which may be used for a workshop, home office or home-based business. The building is owned by a private company, which is owned by its occupants. Occupant shares may be freely sold.
