This does seem to be the case. 4 Economic status of the area.

The first two are those most closely linked5.URBAN OPEN SPACES- with the home because they are the physical setting within which the CASE STUDIES home is placed. Community gardens may be associated with a small group of family houses, a small block of flats for professional people or perhaps a group of bungalows for the elderly. Community gardens are thus shared physically but the use of them may not be a shared experience—it may be that one might be the only user at a particular time.
