台灣在高齡化與高房價衝擊下，住宅居住空間因需長時期的使用而使得變動之需求日益俱增。本研究藉由開放建築理論中之「支架體」與「填充體」系統分離及二階段營建概念，並結合無障礙環境與通用設計等觀念作為設計操作的理論基礎，模擬一套集合住宅居住單元適應「全齡化」變動模式，提供住屋（硬體）與使用者生活需求（軟體）間互動方式。本研究進行程序如下：第一階段：蒐集相關文獻與國內近10年來的集合住宅案例；瞭解國內集合住宅居住單元演變；第二階段：依開放建築理論，檢視前述國內集合住宅案例應用開放建築理論的區別支架體與填充體等二階段營建之可能的變動情形，以順應使用者生命週期各階段之改變；第三階段：透過圖像模擬，探究適應全齡化變動後的空間組合，提供終生住宅設計與實務變動參考依據。本研究獲致如下成果：一、經模擬分析可得知，業界各房型集合住宅居住單位均能夠符合使用者於健康期使用，但由健康期邁入障礙期時，部分房型居住單元空間無法適應其變化需求。二、經情境模擬，提出國內集合住宅常見的各房型單元，於使用者進入障礙其與臥床期時所需的空間尺寸。

Under the impact of aging and high housing prices in Taiwan, the demand for changes in residential space has increased due to the need for long-term use. Consequently, this research is based on support and infill separation system and two-stage construction by the open building theory. Hereafter, the concept of a barrier-free environment and universal design are combined as the theoretical basis for design operations. A residential unit is developed to adapt the variation mode of the aging process and provides a means of interaction between the housing （hardware） and the user’s living needs （software）. The process of this research is mainly divided into three phases: Phase 1: To collect the data from relevant literature and practical case, which included a combination of barrier-free environment and universal design concepts, as well as to understanding the evolution of domestic residential units. Phase 2: Explored the possible changes in the two-stage construction of the support and infill in the overall system of domestic collective residential from the perspective of open building theory, in order to comply with the changes in each phase of the lifecycle. Phase 3: Explored the post-change spatial combination through image simulation to provide a basis of reference for lifetime home design and practical construction, based on previous design results. The results of this study could be found as follows through the analysis and simulation phases: First, the commercialized residential units are suitable for users in healthy periods. However, these residential units are unable to change the space configuration to suit the requirements of users’ need, when the users are stepped into the obstacle period from the health period. Second, proposed the recommended values of the space size for each house type units in the obstacle period and bed-reclined period.
