How is the "new" neighborhood different than the "old" neighborhood in the novel, The Two-Family House?

Mort, Abe, and their families move into a new neighborhood after the company gets a boost and becomes more profitable. This is also the neighborhood where Sol and his family lives. The houses are larger, and each family has much more space than they had in the two-family house on Christopher Street. The neighborhood is not described in great detail, except as is necessary for creating the action that takes place there.
