Since its founding in 1989, the office of Gigon/Guyer Architects has designed a truly impressive array of projects. Among the most significant are museums, residential buildings, office buildings, and mixed-use constructions. The recently completed Prime Tower and the associated buildings on the Maag site in Zurich have received international recognition. The monograph offers a deep insight into the architectural understanding of Annette Gigon and Mike Guyer. The diverse concepts and various applications of design, material, form, and color used in their projects are presented in a detailed documentation of their work, which includes photographs, plans, and short texts. Three essays and a discussion between Patrick Gmur, Martin Steinmann, and the architects provide profound reflection and contextualization.
