The over-riding principle of Wright's Organic Architecture was to provide a beautiful place for the client to live or work. This was accomplished by eliminating things that cluttered the architecture or site, and this , in turn, resulted in simplicity of design which Wright referred to as "form follows function." What followed was a building with the minimum of materials exposed to view.
In his early designs the comparison is made between the typical Victorian home of the period and Wright's own Home and Studio. The Victorian home might have severeal materials used for siding (clapboards and shingles of two or three shapes) painted in a variety of colors. His own home was sided with only shingles and these were finished with a brown creosote finish - a much less complex scheme that was also more easily maintained.
The Home and Studio interior was painted with earth tone colors and decorated with stenciling designed by Wright and Louis Sullivan. Compare this to the Victorian scheme of different complex wallpaper patterns and borders for each room.
