Most cohousing communities have a common house - a building used for shared resources and activities. Often this includes a kitchen and dining room where residents eat together regularly - once or twice a week or more - and take turns to cook. It may also include guest rooms, a laundry, play room, workshop - whatever the community decides it wants and can afford. 'Guest rooms in the common house may allow people to choose a house with fewer bedrooms, saving them money. Office space or meeting rooms may be offered as a resource for the neighbourhood.
