The future of science fiction architecture is at the Brooklyn Public Library.

Now through May 15, visitors can see the top designs submitted to a global competition hosted by the forthcoming Museum of Science Fiction being built in Washington, D.C.

Entrants competed to design a "preview museum" that's opening at the end of this year, ahead of the full-scale facility, which will then be completed within the next five years.

Included among the nearly 40 entries on view in the Grand Lobby of the library's main branch is the winning design, which was selected from among more than 400 submissions from around the world.

"It was a wonderful surprise and honor to be selected among so many beautiful submissions," said Emily Yen, 26, a Rhode Island School of Design graduate who designed the winning model, a semitransparent cube. "The team of people bringing the preview to life is such an energetic, ambitious group."

The 4,000-square-foot portable preview museum will tour other cities before being added as a wing to the full-scale museum.

The library hopes the exhibition will offer a cultural hub where people can appreciate and share their interests in both architecture and science fiction.

"We feel so fortunate because it's the kind of exhibit that engages Brooklynites," said Barbara Wing, a library spokeswoman. "We're getting a lot of people through our door, so it's really wonderful to offer a space where they can interact and engage with one another."

The library will host a number of programs associated with the exhibit over the next few months, including a weekly science fiction film series.

When it opens, the Museum of Science Fiction will be the first museum to focus on the history of the genre, with the preview museum -- and, now, Brooklyn Public Library -- giving people a sense of what's to come.

"We want to celebrate science fiction, the role it plays in our society and how it has brought imagination to reality," said Jonathan Spencer, a spokesman for the museum. "We're excited to have the exhibition start in Brooklyn to gain an even larger audience."

"The Museum of Science Fiction: Winning International Architectural Designs" is on view now at the Brooklyn Public Library's Central Library, 10 Grand Army Plaza, Park Slope, 718-230-2100, now through May 15. For more, visit bklynlibrary.org.
