structural plan and sections of ceiling slab
The architecture of the underground museum is an expression of the design of its structure. A grid of columns spaced at 4m centers sit on a continuous raft slab. This grid erodes to allow the galleries to weave around the existing trees on site. The pleated ceiling slab, also based on the grid, thins at the point where the moment of the beam is lowest and expands at the locations of the columns. Skylights intercept this slab at every second grid module to allow sunlight to filter deep into the gallery spaces.
