US-based practice Allied Works Architecture has unveiled the final design for the Clyfford Still Museum in Denver, Colorado.
The design features a 28,500ft² building made of concrete, which will house works and artifacts of the abstract expressionist painter, Clyfford Still.
The two-storey building will be built at a cost of $29m secured from private funds.
The museum's irregular exterior concrete surface captures light to create subtle shadows, which give the structure a variable façade.
The building is expected to open in 2011, according to the Denver Post.
