New York’s Museum for Africa Art is 22 years old, but it’s lived a nomadic existence. “With 90,000 square feet, including 16,000 square feet of exhibition space, the building will give the Museum for African Art a long-coveted base. Officials hope to break ground in the spring of 2008 and complete construction by the end of 2009. The estimated cost is $80 million, of which $49 million has been raised, including $12 million from the city.”
