Competition projects and abandoned plans are prefigurations that inherently possess a provisional, sketch-like quality. In their suggestive representations, we find bold ideas, utopias, and the power of strong gestures. Therefore, we have decided to dedicate this volume exclusively to designs that are usually left to oblivion. Hubertus Adam, a recognized expert in contemporary architectural discourse and architectural history, illuminates the thirteen imaginative and exciting projects by Annette Gigon and Mike Guyer, placing them within the broader context of their work. The Zurich architects Annette Gigon and Mike Guyer have been among the most important Swiss architects for over ten years, and their work is closely followed in the international arena.
