This publication is the follow-up to the highly acclaimed book eVolo Skyscrapers. 150 new skyscrapers submitted to the eVolo Skyscraper Competition are categorized and examined. These super-tall structures take into consideration the advances in technology, the exploration of sustainable systems, and the establishment of new urban and architectural methods to solve economic, social, and cultural problems of the contemporary city; including the scarcity of natural resources and infrastructure and the exponential increase of inhabitants, pollution, economic division, and unplanned urban sprawl. | eVolo Skyscrapers 2 by Carlo Aiello, Paper over Board | Indigo Chapters
