Reflex architecture should be about clear and simple ideas. Sometimes it is about creating room for dialog and communication between us or to find practical solutions for daily business. It may also involve a combination of different materials, or the interaction between light and space (extract from the introduction of the book no 15). Given that Reflex is celebrating twenty years, we designed an appendix of the last five years of work to the compulsive 15 year book in which they share a number of selected projects which was carried out in close cooperation with their clients. The books come wrapped with a specially customized belly band and will be handed out to all current and future clients.
