bjarke ingels group (BIG) has completed the gammel hellerup gymnasium, a new sustainable sports facility for old hellerup high school in denmark, bjarke ingels’ own alma mater. characterized by a long span undulating roof, the subterranean multipurpose hall is a welcome update to the existing yellow brick building and expands on the human-scaled architecture that so characterizes the existing building. the placement of the volume five meters below ground ensures a climate-controlled environment and relatively low environmental impact.

the gestalt of the architecture is a soft, curved wooden roof that serves two functions as an interior and exterior skin. above grade, the structure behaves as an informal meeting space and long social bench; while the ribs render the interiors an uninterrupted, open plan space. aside from being completely geothermally heated by solar cells, the gym employs passive lighting strategies like a number of skylights the lend a visual airiness to the raw concrete walls. sinuous rafters lend a dynamism to the interior, in part due to a striking use of solid ash. the white-pigmented wood also clads the high-performance sports floors with built-in underfloor heating. this inner envelope boasts the world’s lowest construction height for the specialty flooring crafted by local experts at junckers sports floor.
