Wright was both the most gifted designer and the severest critic of skyscrapers. As early as 1896, when the idea of a supporting riveted skeleton was barely out of its infancy, he was working on a new means of supporting the weight of tall buildings—a means that would provide added strength, lighter construction weight and cost, more floor space, and vast new design possibilities.Briefly stated, Wright's idea was to replace the supporting skeletal framework with a centrally situated tubular shaft from which the floors of the building would be cantilevered, much as the branches of a tree are "cantilevered" from the trunk. In addition to supporting the structure, the tubular shaft would contain the elevators, washrooms, ventilation ducts, and other things that ordinarily take up an unnecessarily large amount of floor space. The best architectural expressions of his revolutionary concept of the skyscraper are the S. C. Johnson building in Racine, Wis., and the H. C. Price office and apartment building inBartlesville, Okla.
Recent Developments. With the destruction by international terrorists of
the World Trade Center on Sept. 11, 2001, observers called for a cessation of competition over height and a renewed emphasis, instead, on quality, aesthetics,and meaning for the local community. There was also a great increase in interest in designing for safety and security, with encased steel columns, new fireproofing standards, and improved emergency exits becoming the norm.Some tall buildings—such as Taipei's Taipei 101 and Shanghai's World Financial Center—were already under construction or in their final planning stages when the September 11 tragedy took place. As a result they had to adapt midstream to the new safety measures. So well did they do so, however, that public worries over extreme height began to be pushed aside, and the race for the tallest building resumed.

懷特是最有天賦的設計師和摩天大樓的最嚴厲的評論家。 早在1896年，當支持的被鉚牢的骨骼的想法幾乎沒有是出於它的初期，他在工作支持將提供增加力量、更輕的結構重量和費用、更多地板面積和浩大的新的設計可能性的重量新的手段高大廈手段。簡要地陳述，懷特的想法是用大廈地板是懸臂的一個在中心位於的筒形軸，替換支持的骨骼框架，因為樹的分支從樹幹是「懸臂」。 除支持結構之外，筒形軸將包含電梯、洗手間、通風道和多餘地通常佔去很多地板面積的其他事。 他的摩天大樓的革命概念最佳的建築表示是S。 C. 約翰遜大廈在Racine、Wis。和H。 C. 定價辦公室和公寓inBartlesville，奧克拉荷馬州。
世界貿易中心在9月。 11日2001年，觀察員要求競爭的停止在高度和更新的重點，反而，對質量、美學和意思為地方社區。 也有在興趣的巨大增量在設計為上安全保衛，與被裝箱的鋼專欄，新的耐火的標準和改善的緊急出口成為準則。某一高大廈這樣，臺北的臺北101和上海的世界財政已經中心是建设中或進入他們最後的計劃階段，當9月11日悲劇發生了。 結果他們必須適應中途新的安全措施。 那麼很好他們如此，然而，公開憂慮極端高度開始被推擠在旁邊和種族為被恢復的高層建築。
