The New York Times announces the Frick’s proposal to add a six-story addition to the museum that would open up the upstairs of the original mansion and offer a roof garden for the museum:

“We and our public revere the authenticity, the intimacy of the space,” said Ian Wardropper, the museum’s director. “So this is a responsibility we take very seriously.”

The Frick’s plan has yet to be presented to its neighbors. Mr. Wardropper said the Frick “will be responsive to their concerns and transparent about the process.”

The project — which would increase space by nearly a third — will also require the approval of city landmark officials because it entails adding to the mansion, and is likely to draw scrutiny from some neighbors who live on the quiet residential blocks surrounding it.
