The Kimbell Art Museum in Fort Worth, Texas has completed its Piano Pavilion, a glass, concrete and wood structure that has tripled the institution’s gallery space. The addition, which was designed by architect Renzo Piano, will also house classrooms, an expanded library, underground parking and an auditorium.

The new building sits 65 yards from the museum’s original structure which was created in 1972 by Louis Kahn, Piano’s mentor. The two structures are adjoined on the Piano Pavilion’s western side, seamlessly merging the new with the old. The Piano Pavilion will house the Kimbell Museum’s permanent collection, which includes European and American art and antiquities as well as Precolumbian and Oceanic art.

The Kimbell Art Museum, which is free to the public, will officially open its Piano Pavilion on November 27, 2013.
