some to experiment with unusual materials and factory<br />

procedures. Many realized that industrial practices<br />

like the use of standardized parts, preassembled<br />

pieces, and simple construction systems could<br />

significantly reduce costs. Wright was actually an<br />

early proponent of a type of prefabrication with his<br />

American System-Built houses of the 1910s. For Wright<br />

and others involved with such explorations, the most<br />

important issue was how to maintain quality, to keep<br />

the homes from becoming cheap, repetitious minimalist<br />

boxes. 10<br />

Wright found a solution with the Usonians. Although<br />

the Usonian houses would come in a variety of<br />

shapes and sizes over the years, they all shared common<br />

features. First of all, they were placed directly<br />

on the ground. Wright did not believe in basements,<br />

and preferred to rest his houses – even back in the<br />

Prairie School days – on a concrete slab. For the Usonians<br />

he employed the slab not only as a base for<br />

the house, but also as the bed for a radiant heating<br />

system. Pipes enclosed in the concrete circulated<br />

hot water; the pipes transferred their heat to<br />

the surrounding concrete, which warmed the air at<br />

floor level, which in turn radiated upward through<br />

the house. As a result, the Usonians did not require air<br />

ducts, radiators, or dropped ceilings since the entire<br />

system was contained within the floor. Wright did not<br />

invent the ancient practice of radiant heating but<br />

did popularize it as a low-cost alternative to forced<br />

air systems.<br />

Wright also abhorred garages. Like basements, he<br />

felt they accumulated unnecessary clutter and<br />

could be avoided. So he designed the Usonians with<br />

carports instead of garages. Flat roofs, which could<br />

be built with less difficulty than standard pitched<br />

roofs, eliminated the need for “ugly” gutters, and<br />

emphasized the horizontal appearance that Wright<br />

favored. The Usonian houses were planned using a<br />

grid system which allowed contractors working without<br />

supervision from Taliesin to easily construct the<br />

house and imposed an order and uniformity on the<br />

whole. These decisions, along with the rejection of<br />

the basement, led to a house that was simpler to<br />

build. And simplicity was the key to the Usonians –<br />

not just in design and construction, but also in the occupants’<br />

anticipated lifestyle. “That house must be<br />

a new pattern for more simplified and, at the same<br />

time, more gracious living; necessarily new, but suitable<br />

to living conditions as they might so well be in<br />

this country we live in today,” Wright announced in<br />

1943. 11<br />

One of Wright’s most unique Usonian innovations<br />

came in the form of a new type of wall. He invented<br />

a sandwiched panel wall consisting of identical<br />

board and batten siding on the interior and exterior<br />

enclosing a core of plywood covered by tar paper.
