BLUE and other shapes 2" is a book that really makes you think about how we live in cities. As the title implies, the book is the revised and expanded imprint of the original title "BLUE and other shapes" from 2019. The original book certainly met with an enthusiastic response and in this second edition, the text is extended, giving greater depth and more explanation. Many photographs speak for themselves, others don't, and these need a helping hand. Since the first edition, the climate debate has intensified, and global temperatures have continued to rise unabated. The pandemic has swept across many different societies such that we ought to see new norms and lifestyle patterns emerging. New generations with new forthcoming technologies can be expected to introduce a new set of lifestyles and awareness rather than the one we have seen the back of. This book is an inspiration to that movement. Sustainability is one of the themes running through the essays that make up the narrative. Sustainability in broadest sense where the human, aesthetic side of sustainable quality is also brought into the picture. The book is about the human spirit as it is interpreted through the materials and substance of our built environment. The design of "BLUE and other shapes 2" introduces an original way of using images as a photographic debate about the future of our built environment. In many ways, this new style can be compared to a physical version of an online platform.
