Development of the System on the Partial Reconstruction of Condominium Building

日本《共管建筑物法》要求对建筑物进行整体拆除，以重建共管建筑物。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，对旧公寓进行改造和改造的方法。我们将这种方法定义为“部分重构”的新概念。通过比较共管建筑和公寓楼(作为公共住房)来验证这一概念的可行性。结果如下：1)我们提出了夹在相邻单元之间的共用墙可以开放连接这些单元的思路，并且连续的三个单元可以是以新的共用单元为公共元素划分中心单元的两个单元。2)我们调查了各种类型的共管建筑的扩建或扩建。3)我们可以分为12种类型的共管改建。并对单位用途的改变或共管所有权模式的部分转换给出了新的定义。4)在以后的几年里，在共管建筑中会出现许多空置的单位。因此，我们研究了关闭单元或减少建筑面积的方法，以避免公寓管理效率低下。5)我们通过对外国公寓重建和终止的比较法律研究，澄清了对日本法律制度的适用性问题。6)最后，我们坚持认为，公寓所有人可以以多数票决定部分重建公寓大楼的重要性。

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.
