NIL was established 70 years ago, and our members have since then played an increasingly important role. The overarching theme of the 70th anniversary in 2015 has been ‘From private to public space’, which means that our members have moved from mostly working with architectural solutions and decoration in private homes, to today also being responsible for interior architecture in public buildings. This is an exciting journey that says a great deal about how the profession’s influence in society has changed. Today holds great importance, with a measurable effect on logistics and flow in buildings and institutions.
