This book, `The Force is in the Mind. The Making of Architecture´ traces the tools of architects. The respective tools used to formulate ideas allow conclusions to be drawn about the architecture that is built. For tools, techniques of representing the communication of an idea all have their technical possibilities, limits and conditions. This problem is deciphered by Elke Krasny's project of selecting architectural offices for this project on the basis of their different working methods. A unique look through the keyhole into the intimacy of architectural production.
