台北市之都市住宅在快速都市化過程中,住宅發展以積層集合住宅作為主流。隨著高級住宅之形式逐漸由郊區別墅轉為積層集合住宅,加上市中心土地取得日益困難下,大坪數積層集合住宅逐漸成為開發商之銷售訴求。本研究以台北市建管處所列管之資料,以平均每戶樓地板面積大於55坪之積層集合住宅案例作為研究對象,透過竣工圖面之分析與測繪,以時間軸、基地規模與室內空間規模等研究視點,企圖由供給實態、住棟構成與住戶平面計畫等三個階段,綜合呈現台北市大坪數積層集合住宅之發展面貌。 研究結果顯示出,80年代後期開始,台北市大坪數積層集合住宅之供給快速發展,且呈現出高公設比、低建蔽率、高層化與低戶數密度之供給特性。此外,住棟構成類型方面,則呈現較為單純之發展,其住棟單元類型以〔梯廳型〕為主;而住棟形態和住棟配置則分別以〔塔型〕與〔單獨型〕為主。而住戶平面計畫方面發現,隨著時間推移與室內面積的增加,逐漸朝規劃彈性較高之類型發展,以減少二次設計所造成之浪費。同時,以室內面積50坪以上(或樓地板面積80坪以上)作為分水嶺,入口類型採〔玄關型〕與〔雙出入口〕之比例明顯增加,而個室空間之比例也明顯轉為增加衛浴空間或設置更衣室等個室附屬空間,是大坪數積層集合住宅之重要空間構成特徵。
During urbanization of urban residence in Taipei, “Multistory Apartment Building (MAB)” becomes popular. Meanwhile the type of hi-end residence has turned from villa to MAB. Developers boost sale appeal to large interior space MAB due to the scantiness of land bases in downtown area. We use cases of MAB whose average floorage is greater than 180 square meters as our research sample. Our viewpoints are focused on time sequence, scale of site area, and interior area in order to present three stages of architectural planning included housing supplement, building plan and dwelling units plan according to the analysis and measurement of approved working drawings provided by Building Administration Office of Taipei City Government. The results of our research show that the rising supply of large interior space MAB started from late 80’s and the characteristics are high ratio of public utility, low coverage ratio, high-story and low residential density. The development of building form tends to centralized. The form of building units, the building structure, and the building form are mainly with elevator hall, square and single individually. As time goes by and the increase of interior area, dwelling units plan is inclined to flexible planning to reduce the waste of second design. Meanwhile, we find that an interior space of 165 square meters is a crucial point for the type of entrance. Entrance hall and two entrances are more popular in which interior space is greater than 165 square meters. Non-common space is moving to enlarge subsidiary space, such as bathroom or locker room. These are important characteristics of architectural planning of MAB.
