After half a year’s construction, OPEN's Dune Art Museum topped out recently. The wooden formwork for thin shell cast-in-place concrete reveals the sophisticated and powerful structure of this building. The site lies in a natural sand dune zone on the seashore of Qinhuangdao, China. When the building structure is completed, sand will be filled back in between and on top of the “art cells”, and the dunes' original state will be restored. Except for the skylights, openings and a viewing platform that appear floating in the sands, the building will quietly disappear in the dunes by the sea.
