The aim of this study is to clarify the spatial recomposition of row house and alley on Nakazaki area in Kita-ward, Osaka-city. I conclude the results as below from the data mostly based on the field survey. In case of row house conversion I could find five methods; elimination, installation, removal, renewal and material exchange. Row houses can adapt new functions flexibly by these five methods. Alleys can also adapt changes caused by row house conversion. Beside art objects and signboards which are situated in front of these conversion shops, domestic articles such as bicycles and air conditioning units outside can be seen. Flexibility and redundancy of row house and alley could be indicated.
