In the spring of 2015, The Met announced plans for a $600 million expansion (to house its modern and contemporary art collections) to be designed by David Chipperfield. But by the following summer, reality had sunk in for the cash-strapped museum, and the plans were put on hold. The museum took a further beating earlier this year when it announced that the expansion won’t get underway for at least the next six years because of financial concerns. Instead, the Met will focus on replacing the aging skylights and roof above the European paintings gallery.

The American Museum of Natural History’s ambitious $340 million expansion plan got the Landmarks Preservation Commission’s approval last October, and work is now ready to move forward on the Richard Gilder Center for Science, Education, and Innovation. The museum will have to demolish three buildings on the campus to make way for the Studio Gang and Davis Brody Bond-designed expansion. It hasn’t been all smooth sailing, however: The project initially did not have the backing of Upper West Side residents, though most came around eventually. This new wing, dedicated to its education and innovation programs, is set to open in 2020.

After a fierce community backlash, the Frick Collection decided to nix plans to build a six-story addition on top of its landmark building, and instead chose a more subdued expansion. Last October, the museum chose Annabelle Selldorf to lead that effort, with the preservation experts at Beyer Blinder Belle signing on to the design team in March. The expansion will open the building’s second floor to the public for the first time, preserve its beloved garden, and create new gallery space, among other features. The design is set to be unveiled sometime later this year or early next year.

Last December, this beloved Washington Heights museum shuttered for what is scheduled to be a two-year renovation. Maria Romañach Architects have been hired to upgrade the building’s infrastructure, make it more accessible, and restore parts of the overall structure. This $15 million renovation, which has been made possible with contributions from the Parks Department, the Manhattan Borough President’s Office, and the City Council, will wrap up in the fall of 2019.

After three years of construction, the New York Historical Society recently debuted its Henry Luce III Center, including a new Center for Women’s History, on the fourth floor of the museum. It’s the first such space in the entire country, dedicated to exhibitions on women’s role in the history of the United States. The center features a 1,500-square-foot gallery for changing exhibitions, space for smaller exhibits, and a permanent, interactive exhibit called, “Women’s Voices.”

After years of operating in a smaller space, Harlem’s Studio Museum is set to get a major upgrade courtesy of David Adjaye (who recently scored a home run with the design of the National Museum of African American History and Culture in D.C.). He’s designed a new five-story home for the museum, which will rise on the site of its current space on West 125th Street. Despite some renovations at its current facility, the museum is so small that it has to shut down every time it preps for a new exhibit. The new $122 million building is being made possible from contributions by the city and the Ford Foundation, and construction is supposed to get underway sometime this year.

In just a couple of months, the Tenement Museum will debut a new 10,000 square-foot facility above its gift shop at 103 Orchard Street. For years now the museum has had to contend with a growing number of visitors, often having to turn them away because of a lack of space. This new space will have a visitor’s center and classrooms, as well as recreate homes of past residents.

The Brooklyn Historical Society will soon unveil a second location at Dumbo’s Empire Stores redevelopment. This new location also comes with a gift shop, and the inaugural show here focused on the photos of Brooklyn’s evolving waterfront over the decades. The century-old warehouse that is now Empire Stores welcomed its first tenant, West Elm, in August last year, and more tenants are due to follow suit.

Following its expansion in 2013, the Queens Museum is now getting ready to add a large library space to its existing facility in Flushing Meadows Corona Park, along with classrooms, workshop spaces, and an art storage facility. This part of the expansion will also be designed by Grimshaw Architects (the same firm that worked on the 2013 expansion). Once complete, the library facility will span 5,500 square feet, be located on the first floor of the museum, and function as a Queens Library branch. Construction on this phase of expansion is set to get underway sometime next year with a completion scheduled for 2020. This overall expansion will cost $15 million.
