Cities develop at a rapid pace, creating an almost endless cycle of new architectural styles. For some architects, it is considered vital that a building reflects the current culture of a city, but for others, architectural progression is a higher concern. And when the latter is applied in the built environment, controversy is rarely far behind. This book begins with an academic debate and then selects works from Toyo Ito, Zaha Hadid, Rem Koolhass, Renzo Piano, Frank Gehry, all of whom have won the Pritzker Architecture Prize. Each project is analysed from its design concept to its completion. The controversies that surrounded the works are discussed, as well and the way each work is interpreted by its viewing audience. The way the buildings are being utilised is displayed. It is hoped that in reading this title even the lay person might understand the reasons behind disputes over the style and form chosen and gain more insight into what makes architecture successful.
