The project for the new halls of the Humboldt and Max Planck Society uses natural light and inflects it into the workspaces and research labs. The placement of the indoor volumes is therefore determined accordingly to the context. Their arrangement, much like the weft of the envelope of the building, changes intensity to create a variable grid-scape. At night-time, the building reveals the spatiality of its interiors, a lantern for knowledge and work in the heart of Berlin. A new idea for work-offices and research spaces that explores the theme of versatility and transparency.
