So, we put forward the concept of " fit to reside in " just by building up a kind of walking space of much proper and many ideas so as to break single transportation function of exterior space of previous living community. so that we can cause the activities and intercourses of residents in walking space area, shape an interact and parallelism between the walking space which contains abundant layer and contents and diversified lives of residents, further build up the approbation of the residents to live area thus
所以，我們提出「適宜居住性」概念，就是通過建立一種多適、多意的步行空間，打破以往居住社區外部空間單一的交通功能，從而引發居民在步行空間領域的活動與交往，讓具有豐富層次和內容的步行空間與居民多樣化、多元化的生活形成一種互動與對應，從而進一步建立居民對住區的認同。
