Arlington
Housing in town centers is easier to service than outlying housing both in terms of infrastructure and also in terms of transit.

Arlington
This infill housing is on a side street within a quarter of a mile from the center, a distance people walk comfortably.

Amherst
This housing was built on a former farm. Because of the dense siting, the farm land and farming activity remain. The higher density also brings down the per unit cost of housing.

Holyoke
A new town is created within an old industrial city.

Canton
By mixing housing and commercial uses in the same structure as with these apartments over a store, the area gains a 24-hour use and downtown residents can commute by walking to a nearby train station.
