The Museum of Fine Arts, Boston (MFA) will open its new wing and courtyard on 20 November following a $504m expansion programme.
Foster + Partners collaborated with CBT / Childs Bertman Tseckares and John Moriarty & Associates, which served as the general contractor for the project.
Landscaping works were designed by US-based landscape architects Gustafson Guthrie Nichol.
The new 121,307ft² wing for the Art of the Americas features 53 galleries, studio and office spaces, and meeting rooms.
The four-storey wing features a central glazed glass building flanked by two pavilions of glass and granite, according to artdaily.org.
The 12,184ft² Ruth and Carl J Shapiro Family Courtyard features 504 large panels, which are supported by a steel frame and offer a meeting place within the MFA.
A new 8,280ft² Ann and Graham Gund Gallery is located below the courtyard.
In addition, the museum's historic building, visitor centre, numerous galleries and conservation laboratories also underwent renovations, which were completed in 2008.
The museum was originally designed by architect Guy Lowell.
