The archive depot is a functional steel shelving unit surrounded by brick facades. Artificial light was not considered safe enough, instead daylight can reach all floors through skylights, windows and grate floors.
We managed to build new office space in this building without removing any structural components. How did we achieve this? The offices come in boxes with extra height, to maximize the available daylight and views. We used the space between these boxes and the existing façade to ventilate excess heat in summer, while in winter the cavity is an extra insulating layer. Glass floors make sure the daylight reaches even the lowest floors. In the center the existing shelving showcase the ingenuity of the original solution.
