New York’s Whitney Museum has a new expansion plan. It calls for a new, nine-story building just a few feet south of the current museum. “The new plan, by Italian designer Renzo Piano, is “more moderate” than previous iterations, said Adam Weinberg, the Whitney’s director. “What we want to do is balance the needs of preservation and the needs of the neighborhood with making great architecture,” he said. Piano’s design calls for demolishing two brownstones next to the museum, and using that space for a new entrance that would feed onto a plaza.”
