This is a large question, impossible to answer in a simple or definitive way. Yet, appreciating why and how architecture matters is essential for any clients, communities or governments to support the work that architects do. This question is also key for architects, who explore, interpret and communicate the value and potential of good design. A basic purpose of any architecture policy is to respond to this question in a way that resonates with the public, motivates decision makers at all levels of society, and helps design professionals demonstrate the impact and value of their work.
