San Francisco Museum of Modern Art (SFMOMA) is set to reopen next month, following three years of renovation.
The expansion and modernisation of SFMOMA was carried out by Norwegian architecture firm Snøhetta.
The 21,5000ft2 expansion increased the existing gallery space by three-fold.
SFMOMA said that the new and renovated indoor and outdoor galleries enables the display of its holdings of modern and contemporary artworks.
The expansion's façade features more than 700 uniquely shaped and locally fabricated fiberglass reinforced polymer panels that form rippled patterns with the movement of light and shadow naturally.
Snøhetta founding partner Craig Dykers said: "Wonderful daylit staircases lead visitors from floor to floor, the galleries create a comfortable viewing experience of the art, and terraces allow for moments of repose, to be reinvigorated by fresh air, sunlight and vistas of the city between galleries. The visitor should sense that the building is inspired by one of the great cities of the world, San Francisco."
SFMOMA's newly renovated Phyllis Wattis Theater houses a Constellation acoustic system from Meyer Sound, which also installed sound solutions throughout the museum.
The Wattis Theater screens archival film and offers 4K projection.
The new museum entrance adjacent to the glass-walled Roberts Family Gallery, allows visitors to enter the museum through Schwab Hall and a set of maple-faced Roman steps provide an informal public gathering spot and seating area.
Gina and Stuart Peterson White Box at the museum supports a variety of performances, events or large scale artworks.
SFMOMA's 10-storey expansion integrates with the original Mario Botta-designed building.
The museum also includes Koret Education Center with a resource library and studio classrooms.
