The St Louis Art Museum, US, has got the green light to undergo a $130.5m expansion.
Construction is expected to begin in early 2010 with ground breaking scheduled for 19 January.
The 200,000sq ft new modernist wing designed by David Chipperfield Architects will offer 30% increased public and gallery space.
The new wing stands resembles a modern temple and will be covered in black polished concrete panels, with naturally lit interior spaces featuring skylights and expansive floor-to-ceiling windows.
The building will house a 300-space parking garage below the structure.
The original limestone and brick building built in 1904 was designed by Cass Gilbert and will be upgraded as part of the expansion project with improvements to the galleries.
