建物の種類及び外観に着目したリノベーションまちづくりに関する研究

<p> Japan, which has entered the era of population decline, is at the turning point of urban planning. When shifting from the urban expansion society to the urban shrinking society, it is important not to develop a new urban area by new construction, but to make renovation town using the building stock in the existing urban area. In recent years, renovation community development is being practiced in many local cities, but there are many cases where renovation buildings are scattered in point, and there are not many cases where renovation is practically implemented in plan.</p><p> In this research, we aim to clarify town renovation focusing on the type and the appearance of building. Specifically, 1) changes in buildings by new construction and renovation focusing on the type of building, 2) difference in landscape from the continuity of the elevation pattern of the building, 3) obvious renovation method concerning the appearance of the building.</p><p> As a method of research, firstly, in order to clarify the transition of buildings by new construction and renovation, we conducted a hearing survey on Mr. Isono of the administrator Isono Shokai and Mr. Watanabe, the architect and gathered related materials. Secondly, in order to clarify the difference of the landscape from the continuity of the elevation pattern of the building, by drawing a continuous elevation view as seen from the street in Johnson Town, we analyzed the difference in townscape from the viewpoint of the elevation pattern of the building. Thirdly, in order to clarify the renovation method related to the appearance of the building, the renovation method concerning the appearance of each building was arranged based on the data for each property.</p><p> The following three points were clarified.</p><p> First, there are nearly the same proportion of newly constructed properties and renovated properties. Construction was carried out in newly built properties in a block that was settled in a few years, while renovation properties have been decentralized over a long period of time. There are many US military houses in the renovation property, and intentionally trying to create residential areas that make good use of the old US military houses. Regarding the use of buildings, the use of houses was the majority in 2002, but the use of shops gradually increased. In Johnson Town there is no clear zoning, and in the newly constructed Heisei House it is designed to be available in both the residential and shops.</p><p> Secondly, in the block area on the park side, the elevation pattern of the building is aligned, whereas in the block area on the national highway side the building's elevation pattern is not aligned. It is conceivable that buildings of the same kind were built at the same time in the same block as a factor which is complete. Factors that are not aligned include the unevenness of the types of buildings and the existence of buildings outside.</p><p> Third, as a renovation technique related to the appearance of the building, there are four methods concerning the outer wall, one method concerning the extension, and two methods concerning the deconstruction. These can be said to be a renovation method tailored to the appearance of the US military house. While the elevation pattern varied according to the streets, it is thought that a townscape with unity was formed by performing renovation related to the appearance toward one direction.</p>
