We have an open structure. A certain hierarchy must be, otherwise we are unable to control, but it is conditional place and time. At the same time, I think we have managed to create an environment where we get the best from the individuals who work here. There are many small decisions making throughout, so the architecture is today, it is the only sensible organization because architecture is a mental state as much as physically. «The Petter Dass Museum is shaped by the spirit and place strategy where Snøhetta´s procedural work has been divided into several levels of work.
