The Aspen Art Museum announced last Friday that the second phase of its capital campaign is underway with matching gifts of $5 million, adding to $28.5 million in existing pledges, for a new building in downtown Aspen. City Council must confirm the plans within 30 days, reports the New York Times.

The new Aspen Art Museum will be designed by Japanese architect Shigeru Ban as his first U.S. museum. The proposed 30,000-sq-ft. "transparent' building will feature 12,500 square feet of exhibition space as well the city's only public roof deck with a sculpture garden.
