When, in architecture, one uses a fixed unit and combinations of it, to produce harmony, the effect should be most striking and apparent... as it is … - Ernest Flagg

One of the most ancient and inexpensive ways of obtaining shelter, was to utilize the space under sloping roof rafters. Indian wigwams have no other kind. Where civilization is slightly more advanced, low stone walls are built upon which the feet of the rafters rest.

In the human form, as nature tries to make it, every feature is useful and every feature is beautiful. Each member is perfectly adapted to the function it has to perform; nothing is superfluous, yet the whole and every part is supremely decorative.

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.
