The revised design of the National Museum of African American History and Culture in Washington, US, has been reviewed by the National Capital Planning Commission.
The revised design shifts the building to the southern boundary of the site, making it 17% smaller than the original architectural proposal.
Designed by architect David Adjaye, the new museum features three coronas that wrap the main structure, while the entrance leads to a bridge, pond, garden and access to the main hall.
The architecture team of Freelon Adjaye Bond / SmithGroup won the contract to build the museum in April 2009.
Following final approval from local authorities, the museum is expected to be complete in 2015, according to the Washington Post.
