The profession architect has expanded in recent years, not just in terms of the cultural influences, but equally with respect to scientific advances. The inventive economy has also led to new lifestyle choices and a new role for the architect and architectural practice. We talk of an architecture that is either pre-crisis or post-crisis, the latter resulting in a call for responsible architecture (affordable, sustainable, attainable, and healthy). This development led to changes in the UNStudio practice; with the introduction of Knowledge Platforms and the development from a network to a knowledge practice. Now compiled into an inspiring publication, Knowledge Matters will help architects to run a better studio and to share knowledge.
