原文：
The plan I conceived was architectural and based on the elements of the domestic settlement: hearth, wall, terrace, roof. A fifth main division should comprise the working together of these four elements and embrace high art and, in a symbolic sense, high science. This plan should make apparent the derivation of objects and forms from their primordial motives and style changes conditioned by circumstances.
