The potential of the combined method is examined by measuring the properties of three sets of plans for residential aged care facilities. The first set is a pair of hypothetical, idealized plans, which allegedly reflect the ＂best practice＂ in the industry. The second set comprises a pair of plans for recent Australian designs, and the third set is a pair of plans for South Korean facilities. Results of the computational anatysis of these six plans suggest that social and cultural factors may shape the design of aged care settings and partially explain their international differences. The application of this methodological approach contributes to the understanding of the relation- ship between spaces and their cultural and social properties in the design of aged care facitities.展开更多
