All Apartment and Multi-Family Buildings

A building purpose designed to house more than one household under a single roof or across a single architectural complex, spanning early twentieth century apartment blocks, mid-century housing estates and towers, and contemporary mixed-use residential high-rises. What unites this group is the multi-unit program itself: a building conceived from the outset to serve many separate households at once, which sets it apart from every single-family house group here, whether that house is a plantation house, a villa, a museum-operated historic house, or a modern architect-designed demonstration house built for one family.
