Uncluttered usable space demands peripheral structure forming an enclosure; spaces that harbour the staircase; and toilets are outside this enclosure, ensuring efficient utilization of habitable space. The freedom of arrangement of the layout of rooms is guided by strict structural enclosure constraints, and openings for light and air in the most appropriate places. The open terraces in every unit reflect the response to the local climate. Each unit has three-anda- half sides open for both light and cross-ventilation. Together, the layout brings a sense of connected clusters.
