付加機能を複合した住宅作品の空間構成

摘要

1920年代に始まった戸建て住宅は、仕事をする地域と住む地域を分ける都市計画的なゾーニングに基づいた核家族だけの空間へと純化されていく傾向をもっていた。近年は、都市化による敷地の細分化により家に人を招き入れる設えもなくなり、内に閉じがちになっている。そして、そのことがコミュニティの紐帯を弱め、無縁社会と呼ばれる環境の遠因となっていることは憂慮に値する。%The aim of this study is to clarify the spatial composition of contemporary Japanese houses that have functions other than a dwelling. First, problems of discussion were analyzed on following 4 aspects. Where is the location of the addition functional part and buffer domain in the site? What relations do they (the addition functional part and buffer domain) have on ground level? What is the circulation line feature of the buffer domain? Where does locate the buffer domain in the housing space, interior or exterior? Secondly, relations of the housing part, the addition functional part and buffer domain are represented by diagrammatizing division of volume of the whole construction just as a tree diagram. Finally, by arranging analyzed results as above, we extract typology of data having common feature.
