ROOF, CANTILEVER AND RIFT
Frank Lloyd Wright often said his buildings were like plants that grew from within and came up from the ground into the light. But his work had developed from the outside in and from the top down. Such was a paradox that has gone almost unnoticed: His mature way of thinking about architecture lay opposite the way he took to architectural maturity.
Wright first of all wished to bring architecture into harmony with the land. Hence he had every reason to begin his reforms in the outward look of a building. Its ground plan, academic opinion to the contrary, did not at first play a crucial role; buildings of vastly different appearance, after all, could be constructed from the very same plan. Robert C. Spencer, Jr., saw in 1900 that although Wright consistently tried to reduce the number of rooms on the main floor of a house, this was ânot, generally speaking, an original or peculiar idea. â Visitors from abroad had been quick to remark that the principal rooms in many American houses opened to one another with a surprising informality and freedom. And when he described his own work in 1908, Wright was refreshingly candid:
The exteriors of these structures will receive less ready recognition perhaps than the interiors and because they are the result of a radically different conception as to what should constitute a building. We have formed a habit of mind concerning architecture to which the expression of most of these exteriors must be a shock, at first more or less disagreeable . . . .
The ground plans, he said, were âmerely the actual projection of a carefully considered whole.â Many years later he wrote of the âoriginating idea of modern architecture from the outside inâ and fondly recalled the ânew shapes of shelterâ he had published in Germany in 1910 and 1911:
Quiet mass-outlines extended upon the ground levels in becoming human proportions throughout . . . the early straight-line, flat-plane dwellings built by myselfâhappily and with great hopeâon the midwest prairie I loved . . . . The plan grew more beneficial to human life.
The originating idea proceeded from the outside in, he said, and served to âget the house down in the horizontal to appropriate proportion with the prairie.â16
What happened at the roof and eaves gave the first sure sign that Wright was out to make an architecture all his own. In 1624, Henry Wotton wisely said of the roof that âthough it be the last of this art in execution, yet it is always in intention the first, for who would build but for shelter?â Life in the Middle West demanded shelter; the weather, as Wright said, changed from bitter cold to simmering heat, from long months of drought to sudden downpours, thunderstorms and even tornadoes:
Alternate extremes of heat and cold, of sun and storm, have also to be considered. The frost goes four feet into the ground in winter; the sun beats fiercely on the roof with almost tropical heat in the summer: an umbrageous architecture is almost a necessity, both to shade the building from the sun and protect the walls from freezing and thawing moisture, the most rapidly destructive to buildings of all natural causes.
Spencer in 1900 took pains to explain why Wright almost invariably exaggerated the eaves. They excluded the sun from the upper rooms during the hotter hours of a summer day, he wrote, and provided shade for five or six months of the year. Their soffits, or undersurfaces, reflected indoors a diffused light as agreeable as it was surprising. And as the roof surfaces quieted the whole, the eaves brought a satisfying sense of shelter from sun and storm.17
But the eaves were only an effect of the radically assertive roof. Wrightâs attention to the roof and his affection for the horizontalâboth inspired by his feeling for the prairiesâhad happily coincided. To salute the landscape he projected the roof decisively past the walls and thus exalted the necessary into the poetic:
The climate, being what it was, a matter of violent extremes of heat and cold, damp and dry, dark and bright, I gave broad protecting roof-shelter to the whole . . . . At this time, a house to me was obviously primarily an interior space under fine shelter. I liked the sense of shelter in the âlook of the building.â I achieved it, I believe.18

6. The power of the roof. Taliesin, the architectâs home and studio near Spring Green, Wisconsin, 1911â59.
Wright lowered the roof, lengthened it and brought it closer to the ground [5]. Nothing so distinguished his Prairie years as the expressive power he gave to the roof [6]. And in the best projects from the very end of his careerâsuch as those of 1957 for the Arizona State Capitol and of 1959 for a Fair Pavilion at the Marin County Civic Centerâthe life of the roof still proved characteristic. In his 1908 manifesto, significantly, he wrote first of the roof and then of the foundation and stylobate, the arrangement of the wall up to sill and frieze, the window groups, the plan, ornament, function, relation to client and, last of all, the interior and its furnishings. In the same paper he classified his buildings by roof type, a Japanese custom. (Long before 1905, when Wright first visited Japan, Edward S. Morse had written that âit is mainly to the roof that the Japanese house owes its picturesque appearance. â The extended eaves, Morse observed, were meant to protect the paper shoji screens from rain.) And many of the most engaging drawings Wright published in his Wasmuth portfolio of 1910 were birdâs-eye renderings, which so beautifully illustrated the shape and spirit of his broad sheltering roofs [7]. Much later, Wright pondered the history of architecture, and said the general aspect of manâs earliest dwellings was most affected by the shape of the roof:
Later the sense of roof as shelter overcame the sense of walls, and great roofs were to be seen with walls standing back in under them . . . . His roof was not only his shelter, it was his dignity, as well as his sense of home . . . the roof-shelter became the most important factor in the making of the house. It became the ultimate feature of his building. This remains true to this late day. 19
The outline of the roof could reveal much of the character and sometimes even the identity of a building [8]. Thus when he quoted the derisive words of ThoreauââA sentimental reformer in architecture, he began at the cornice, not at the foundationââWright curiously compounded the irony. For it was precisely at the cornice that he began to show his hand, and he had confessed as much at Princeton University in 1930, when he spoke about the cornice almost ob...
