Development of the System on the Partial Reconstruction of Condominium Building

日本的《共管公寓法》规定，为了重建共管公寓，必须拆除整栋建筑。但许多老旧的共管公寓将继续存在并发挥作用。因此，本研究探讨了在不拆除整个建筑的情况下对旧公寓进行重建和改造的方法。我们将这种方法定义为一个新概念“部分重建”。我们将公寓建筑与公寓房屋（作为公共住房）进行比较，以确认这一概念的可行性。结果如下：1)我们提出的思路是，夹在相邻单元之间的聚会墙能够打开以连接这些单元，并且连续的三个单元能够成为两个单元，使用新的聚会墙作为共同元素划分中心单元。2)我们调查了各种类型的扩建或扩建公寓建筑。我们可以分为12种类型的转换与公寓。我们给出了部分转换的新定义用于单位用途的改变或公寓所有权模式的改变。在公寓大楼里，几年后会出现许多空置单位。因此，我们研究了关闭单元或减少建筑面积的方法，以避免公寓的低效管理。5)通过对外国共管财产的重建与终止的比较法学研究，明确了日本法系适用的问题点。6)最后，我们强调了公寓业主可以通过多数投票决定公寓部分重建的重要性。

Japanese condominium law requires to demolishing the whole of building for reconstruction of the condominium building. But many old condominiums will continue to live and to be useful. So this study examined the methods for reconstruction and remodeling of the old condominium without demolishing the whole of the building. We defined this method as a new concept "the partial reconetruction". We compared the condominium building with the apartment house (as public housing) to confirm the feasibility of this concept.The results are as follows.1) We proposed the way of thinking that the party wall sandwiched between the adjoining units is able to open for connecting these units, and that the continuous three units are able to be two units dividing the center unit using new party wall as common elements.2) We investigated various types of enlargement or extension of condominium buildings.3) We can be divided into 12 types of the conversion with condominium. And we gave the new definition of the partial conversion for the changing of the unit's use or the condommium ownership pattern.4) In the condominium building later years many vacant units will occur. Therefore, we examined the method of closing the unit or reducing floor area to avoid inefficient management of condominium.5) We clarified the point at issue of the applicability to Japanese law system with the comparative legal study on the reconstruction and termination of the foreign condominium.6) Lastly, we insist on the importance that condominium owners can decide by majority vote the partial reconstruction of the condominium building.
