A pool crowns the 12-room, 5,000-square-foot duplex penthouse on sale at 21 Beaver Place in Beacon Hill’s Flat of the Hill area for $11.45 million.

The pool is part of a large deck that also includes a grilling area and an herb garden. And that gargantuan tag—the biggest in Boston in several months—covers four parking spaces, including two in an attached garage.

All totaled, the penthouse includes four and a half bathrooms, six fireplaces, and the potential for five bedrooms.
