Book excerpt: When Frank Lloyd Wright turns his attention to one of the most important personal problems now facing practically everyone in our society - it is a time for rejoicing. The world's greatest architect here meets the urgent problem of suitable shelter for The Family in a democracy, in a magnificent and - as was to be expected - challenging book. Here, presented at last in full detail, is the natural house. The moderate cost houses described in this book and profusely illustrated with 116 photographs, plans and drawings, are houses - of infinite variety for people of limited means - in which living has become for their owners a purposeful new adventure in freedom and dignity. Mr. Wright tells the story of the world famous "Usonian" houses, so that we now see, in text and illustrations, how they have evolved from original conception to final execution. He has also written a step-by-step description of the "Usonion Automatic," explaining just how that remarkable house is built - a simplified method of construction so devised that the owners themselves can build it with great economy and beauty. For this purpose, there are, in addition to Mr. Wright's text, special photographs and drawings of the method and materials, showing clearly how the Usonion Automatic is built.
