大阪近代長屋における改修を伴う新規入居の仕組みと改修の傾向

<p> Many of the Osaka Modern Nagaya row-houses were constructed in the Taisho (1912–1926) period and the early years of the following Showa period, when housing development spread to Osaka’s suburbs to form high-end residential areas. This study summarizes how new dwellers move into Osaka Modern Nagaya, and how these row-houses are renovated, based on field surveys of seventeen cases of recent new dwellers, and consequently arrives at the findings described below. The subjects of this study are Osaka Modern Nagaya row-houses that can be studied through field surveys and interviews by taking advantage of the network of the OPEN NAGAYA OSAKA event and that new dwellers have settled in recently, mainly within the past ten years, to be used exclusively for living or used not only for living but for other purposes as well. Of the seventeen cases, three are owned and fourteen are rented, while four are used exclusively for living and thirteen are used also for other purposes.</p><p> Below is a summary of the findings of this study:</p><p> 1) Almost no information about Osaka Modern Nagaya row-houses available to let is available to general property seekers who adopt the common way of searching real estate information and it is thus necessary to find special real estate websites or agents to move into them, which can pose a hurdle for potential dwellers. At the same time, however, this special condition, under which new dwellers move into these row-houses almost only through connections mediated by community-based real estate agencies or acquaintances, guarantees trust between tenants and landlords.</p><p> 2) When these row-houses are regarded as general real estate properties, it can be said that they are available under advantageous conditions, in terms of convenience of location and price per square meter. In addition, it has been found out that these houses have been highly appreciated and selected for their characteristics that are peculiar to nagaya row-houses, namely that they allow dwellers to use them not only for living but also for other purposes, and freely renovate them, by property seekers who particularly value such conditions. Although only a few of the dwellers had row-houses in mind from the beginning, the atmosphere of the traditional row-houses is very much loved by them.</p><p> 3) The study sums up row-house renovation costs and how they are allocated. The owned houses have gone through relatively pricey renovations, including seismic retrofitting, while it has costed the tenants of the rented houses an average of 2.76 million yen to have their houses renovated. Although tenants of rental row-houses need to bear the cost of renovating their houses themselves, it gives them an advantage of being allowed to freely renovate their homes.</p><p> 4) Bathroom and other water facilities are more likely to be renovated by the owners or tenants of the houses, while seismic and insulation retrofitting is less likely to be carried out.</p><p> 5) Eight items have been set to examine how traditional designs are retained after the renovations. Tokonoma and tatami rooms have been lost in nearly forty percent of the cases, while most cases retain the original planar composition, which has gardens and connected small rooms partitioned with doors and horizontal walls. In cases in which the houses, mainly owned ones, have undergone major alterations, including seismic and insulation retrofitting, many of their traditional designs have been lost. In one case, however, a bold renovation has resulted in a traditional frame becoming presented in an innovative fashion by making the house’s small roof open-timbered.</p>
