Frank Lloyd Wright's 1938 'Dream House' for Life magazine, described here at Life.Com.
"Space," says Wright, in a letter to the clients describing the house, "is characteristic of this free pattern for a freer life than you could possibly live in the conventional house." The house is a two-zoned open and flowing plan "with special privacies, ultra conveniences and style all the while." Said Life magazine in 1938:
Note the L-shaped double fireplace. By means of folding screens, the dining and ground-floor sleeping spaces can be thrown into the living-recreation room and the whole space, treated as a kind of enclosed patio, can be thrown open to the outdoors... For privacy, [the clients] may close off their ground-floor bedroom, leaving it open to the garden, and [their two children] may retreat to their bedrooms at either end of the second floor, which are separated by a guest room in the middle. Mr. Wright has thoughtfully placed [the husband's] office next to the kitchen so that [his wife] can answer the telephone for him when he is away from home...
Life magazine had set up the 'Dream House' series as a competition between traditionalists and so-called modernists. Time magazine called Wright's design a "walkaway [victory] for the moderns ... which reduced the merit of [the more traditional] design to that of a safe investment."
