Park Annex is identified as a Special-Interest Housing location, specifically for affinity housing.

Park Annex was a house that once belonged to members of the Look family who gave Look Park to the city of Northampton. It was also rented as off-campus housing to Smith students before it was acquired by the college in 1920.

Park Annex is in a scenic spot, near the president's house and Paradise Pond. It is a 5-minute walk to the central campus area—with the libraries, classrooms and administrative buildings—and about a 10-minute walk to downtown Northampton.
