A Prospect Park-facing mansion is hitting the market today — for $11 million.

The turn-of-the-century, gut-renovated property at 104 Prospect Park West was designed by famed early-20th-century Brooklyn architect Axel Hedman. It had been owned by a single family for close to a century.

The 1,500-square-foot parlor floor comes with 12-foot ceilings and bay windows that face the park. There’s also a library, a formal dining room with windows that the listing says frame a view of Brooklyn’s oldest ginkgo tree, and a skylit staircase.

Other features include a chef’s kitchen overlooking a rear bluestone patio, and a pass-through butler’s pantry featuring additional storage, a Miele dishwasher and a Sub-Zero wine fridge.

The 1,000-square-foot master suite takes up the third floor and comes with a large dressing room that opens onto the roof of the rear deck.

The home boasts Manhattan skyline views and comes with original details, like pocket doors, stained glass, pier mirrors, plaster detailing and built-ins.

The listing broker is Alex Maroni, of Douglas Elliman.
