NL Architects recently completed the project NS Station, a major office interior revamp over 9 stories right on top of Central Station in Utrecht, the Netherlands. The project resulted from a 2011 competition win where NL Architects made the Thick Walls™ system the conceptual core: big shelves absorb the clutter that normally spreads trough the office - wardrobes, bookshelves, flip boards, archive, bulletin boards. And sometimes even the stairs.
