Essentially a study book for architects, this detailed investigation of the Japanese house is made with a view to its significance for contemporary architectural creation. Walter Gropius in his foreword remarks upon the coherent effort at attaining unity in diversity. Heinrich Engel, a German architect living in the United States, also studies the structure of the house, its use as a physical-psychological shelter, its relationship to the environment, the aesthetic element involved. He sees the importance for current work in the unique relationship that exists between form and space and their cause and motivation. The book takes up technicalities with diagrams as well as photographs. Of definite professional interest in its comprehensive yet concentrated approach.
