Trask's office interior is the result of the rare symbiosis of design, courage and obsession with detail. Everything is natural, nothing is a lie. The massive reception desk, made of translucent LiCrete(C), will not leave you indifferent. Separated only by whiteboards, the bays of work desks follow the organic shape of the building. No one is isolated. Everyone is able to find their way even though there are no corridors. In between work bays the authors scaterred a study room with a library, lounge nests to relax and chill, a focus room for tasks demanding extra concentration. The area is dominated by raw and genuine materials - birch plywood, large format sheet metal, concrete, glass and wireglass. Since the raw plasterboard is used as a decorative surface, one of the less expected challenges for the authors was to assure its quality. It was complicated to explain to the workers that they can not draw and write on the gypsum panels. The walls are decorated by paintings of emerging Czech painters and graphic artists. Every single pictogram was carefully considered. Every last flower has it's place and meaning. Because in many cases, quality seems to be the cornerstone of sustainability.
