本研究企圖從「區域性」的研究視點，針對台北市信義區民間集合住宅，企圖從住戶平面計畫的角度，深入探討該區之空間構成的供給特性與台北市一般民間集合住宅之異同。研究得知，1990年起，信義區的民間集合住宅之住戶平面計畫類型呈現較多樣化的供給特性，自2000年以後則轉以更具彈性之［無隔間型］，以避免「二次設計」時所造成不必要的浪費；此外，大坪數集合住宅之室內入口類型普遍採「雙出入口」的規劃方式作為供給主流；同時發現近年衛浴空間已成為信義區較大坪數集合住宅之主要訴求的供給指標之一。故2000年可視為台北市信義區民間集合住宅之住戶平面計畫供給差異的分界點。

This study mainly explores the variance on supplying characteristics of spaces upon dwelling unit plan of private condominium in between Xinyi District and other area of Taipei City, from the aspect of ”regionalism”. Research results that since 1990, the plan has been providing a wider variety of choices for consumers from the district. However, from 2000, the plan has applied a more flexible ”open-spaced design” to avoid an unnecessary waste caused by ”secondary design”. In addition, most large condominium are designed to have double entrances and exits as a mainstream; it also finds the available space in bathroom has already become one of the main supplying indicators in large condominium in the district over the recent years. Therefore, the year 2000 is a distinctive year on the supplying variance of dwelling unit plan of private condominium in Xinyi District of Taipei City.
