Spatial structure of 56 CCRCs(Continue Care Retirement Committee) which are mainly selected from AIA contest project are analyzed by using space syntax theory. Based on the result of common facility allocation and spatial centrality, three common facility allocation types and six route space integration models are defined. While the analysis shows the central allocation with route connected to a common facility being the highest integration place is the predominant spatial structure of common facility in US CCRCs, the combination of each common facility allocation type and route space integration models provide the fashion of common facility spatial structure in US CCRCs today. Keywords: CCRC, common facility, common space, space syntax. eISSN 2514-751X © 2017 The Authors. Published for AMER ABRA by e-International Publishing House, Ltd., UK.
