The book presents the remarkable history of the emergence in the past two decades of the dramatically new design of multi-tower and multi-functional tall building clusters. Based upon a decade of architectural research, the book provides a definition of the new typology, here termed The Tower Cluster, and its major concepts, design characteristics, and the typological knowledge required to design creative sub-variants. It provides the detailed analysis of a large series of recent case studies of the typology.In addition, the book categorizes various types of sky amenities such as sky pools, sky plazas, outlook decks and other functions that have been, in this new typology, distributed through the vertical order of the tower cluster in order to create a new form of Vertical Campus which contains a designed selection of social, cultural, commercial, and entertainment facilities. The various types of groupings of advanced amenities in multi-story residential buildings, hotel buildings, office buildings, and high-tech headquarters/research buildings are presented and discussed in detail. The design knowledge and architectural knowledge of tower clusters and their vertical amenity structures are defined, and the definition and general application of typological knowledge in design provides to the reader a valuable knowledge base for the future designs of creative sub-variants tower clusters, as well as for their urban and landscape development. Thereby, the highly articulated knowledge component contained in the book becomes a valuable contribution to the future design of tower clusters as well as to the creation of a model of how to define architectural knowledge. It constitutes a brilliant working guide for the design of new skyscrapers. This work is part of a broad historical quest for an architectural medium - a typology of design - that might be capable of transferring certain urban social places to new locations above their traditional ground-based urban locations. That is, this provides a new medium To Socialize the Sky!
