Underground Gallery: An Earth-Sheltered Exhibition Space

Design an underground gallery in the manner of Philip Johnson buried beneath a grass mound so that only a low doorway shows above ground, with paintings stored on huge rotating racks that swing out of the wall rather than hanging in the open. Compose a series of shallow domed chambers in plain white plaster, a bare polished floor, three large circular steel racks recessed into the wall with one swung open to display a canvas, no daylight at all and only concealed uplighting, dim intimate illumination, eye-level view along the chambers, 28mm lens, interior photography, ultra photorealistic, 8K
