From the beginning Wright practiced radical innovation both as to structure and aesthetics, and many of his methods have since become internationally current. At a time when poured reinforced concrete and steel cantilevers were generally confined to commercial structures, Wright did pioneer work in integrating machine methods and materials into a true architectural expression. He was the first architect in the United States to produce open planning in houses, in a break from the traditional closed volume, and to achieve a fluidity of interior space by his frequent elimination of confining walls between rooms. For the Millard house (1923) at Pasadena, Calif., he worked out a new method, known as textile-block slab construction, consisting of double walls of precast concrete blocks tied together with steel reinforcing rods set into both the vertical and the horizontal joints.
