The system of building, described in this work, is intended for repetition. It would hardly pay to adopt it in its entirety for a single house if the matter were to end there. Where the processes and apparatus is used, over and over again, great economy should result; but for a single building, the trouble and expense of introducing so many new or unusual features and methods, might well offset the benefits which should accrue under more favorable conditions. Standardization both of parts and workmanship plays a great part in the economies obtained and standardization implies quantity.
