The organization of public space raises many challenges. Its very nature of being on public display makes urbanism one of the fields of architecture that is most open to debate and controversy. Urban spaces should not only strive for a balance betweeen solid and void in the urban fabric, but they must also be highly functional. All architecture stems from the need to offer answers and solutions to specific problems and demands; these answer and solutions are then integrated into a generally predefined environment with various limitations. This book offers a sample of some of the works that, through their originality. ingenuity and creativity, have found a method of sustainable design. In these designs an interest in nature goes hand in hand with the design, providing beautiful spaces for living in harmony with the environment.
