This study aims to clarify the background and the process of transformation of the Inari-yamashita accomodation housing built for the victims of the Great Kanto Earthquake built in Yokohama City in 1925, which was a 1st-floor wooden tenement house. We found that this housing was one of the two facilities for accommodating the victims evicted from temporary shanties, under the strong intention of social welfare by Yokohama City. And the planning of this accommodation was quite similar to that of the Dojunkwai Foundaation, but this accommodation has used the old materials like king-post-truss from the roof of the former shanties, so in a structural way, this was a big condition of construction of this accommodation. Through measuring this building, we investigated many activities of the dwellers to transform the housing.
