When the alternative form of housing is too costly, too far away and without transport, essential services or amenity, when we are too old or busy to care about the white picket fence and the state of the hedges, we warm to the unattractive bulk of the new unit development.
A new group will leave the safety and seclusion of their own free standing homes to embrace, in an awkward way at first, the concept of living in closer community.
But these are different forms of home. They are not detached. These are attached homes with shared walls, floors, ceilings and facilities and when it comes to sharing property, we have a lot to learn.
