UCCA Dune Art Museum

On a stretch of beach called the Golden Coast in Changli County, on the Bohai Bay in northern China, OPEN Architecture has designed a museum that disappears beneath the dunes, like a mysterious cave hidden in the sand. Coastal dunes form over long periods through wind-driven sand accumulation and are stabilized by the roots of native low shrubs. Locating the museum under the dunes is both an act of reverence and protection: because the museum exists, this stretch of dune will never be leveled, preserving a fragile ecosystem built over centuries. Inspired by children digging in sand, the architects excavated connected cave-like chambers in the dune, echoing humanity's earliest dwelling form and earliest art-making spaces. A series of cell-like continuous spaces houses galleries of varying sizes, a reception hall and a cafe. The main entrance is a tunnel-like opening embedded in the dune; after a long, dim passage, visitors enter a domed reception hall with soft skylight, then emerge into the central gallery, where a shaft of light pours from a high dome, jumping across walls and floor in a quiet, sacred glow. From inside, the sea looks different through every opening and at every hour. A spiral staircase leads up from the dark caves to a rooftop viewing platform on the dune crest, suddenly opening onto sky and ocean. The complex three-dimensional curved shell was hand-formed by local shipbuilding carpenters from Qinhuangdao, who wove wooden formwork from small linear materials and poured concrete. The irregular, imperfect concrete surface is retained, so hand-building traces can be touched. Windows, reception desk, bar, restroom basins and even the cafe's eight tables were custom-crafted. Beyond form, the building pursues sustainability: the planted and sand-covered roof reduces winter and summer energy loads; skylights of varying orientation and size provide all-day natural light; and a low-energy, zero-emission ground-source heat pump maintains stable temperature and humidity.
