south korean studio D.LIM architects has completed a multipurpose facility for CJ, one of the countries largest companies. located at the center’s golf club on jeju island, the subterranean project avoids disrupting views of the surrounding forest and natural landscape. more than half of the volume is dug beneath the ground level, with a large hole subtracted from the roof to filter light through to the spaces below. the circular void is in the shape of the CJ’s official logo, which represents notions of joy – the meeting rooms and workspaces are positioned around this core element to absorb natural daylight and uplifting energy from the sky above.

the project is located on jeju island, in korea, an area known for its natural landscape

the underground spaces consist of meeting rooms and a multipurpose hall, which can be used as a sports facility to accommodate tennis and basketball matches. the sloping roof garden is accessible from the ground, merging seamlessly with the parking to enable one to walk directly on top of it. the shape of the structure also functions as an amphitheater, as more than 300 people can sit on the integrated stone chairs and grass surface for outdoor performances.

most of the volume is inserted underground, so it doesn’t interrupt the surrounding forest views
