In China, the perimeter block typology doesn\u2019t usually return the Floor Area Ratio (FAR) necessary to satisfy inner urban densities. This leads to an over reliance on detached towers to meet FAR requirements. The perimeter block with a tower extrusion however, presents a useful hybrid. The advantages of the perimeter block (positive reinforcement of active urban street edges; well ventilated and naturally lit building interiors; and an internal courtyard that has the options of being private, semi-private-semi-public, or public space) are combined with the capacity of the tower to maximize floor area.<\/p>
