Above the hustle and bustle of Fort Point, there’s a refuge from urban life. With its birch hardwood and limestone floors, floor-to-ceiling windows — not to mention the private enclave up on the roof — this double penthouse on the seventh and eighth floors of the FP3 building is just that.

The main living space has ceilings nearly 12 feet high, and tall windows line this condo from one end to the other. The red-stained birch and limestone intermingle in something like a checkerboard as they flow across the floor in an open design encompassing the fireplaced living room, the kitchen, and a media room that can be converted into a third bedroom, thanks to a retractable wall.

Fort Point tries to preserve its original buildings — FP3 has 92 units and is in a structure built in 1899 — so there is no steel-and-glass monolith opposite this penthouse. Views stretch from the Financial District to Boston Harbor.

The heart of the space is the kitchen, which boasts high-end appliances, including a double gas oven; dual sinks; and flat, dark cabinetry. The marble-topped islands are the star of the space. Imagine a letter O split in half.

Down the hall and to the left is the home’s second bedroom, which has an entrance flanked by closets. The owner calls it the “Zen Room.’’ It offers a great view, and its walls are clad in a mountain black quartzite that looks like curling ocean waves. The porcelain tile en-suite bath, hidden behind sliding doors, has a a shower and a soaking tub, which is positioned next to the windows.

Across from the Zen Room is a full bath, the laundry, and a walk-in closet.

Farther down the hallway, it seems as if it’s the end of the unit — but there are false walls that pull open. One leads to the private elevator to the roof deck, the second goes to the master suite.

The bedroom area itself is about 400 square feet and offers a commanding view, a wet bar, a gas fireplace with a brown marble surround, and sliders to a private deck. The master bath is spectacular. The rear wall is given over to cabinets; the front is full of windows looking out toward the harbor. The multi-head shower is a large circle of frosted glass broken by flashes of clear glass and stainless steel. The bathtub is shaped like an undulating recliner. The flooring is a Marron marble, and the vanity is topped with Crema Marfil marble.

Steps down the hall from the master suite, there is a second, smaller bath tucked behind a false wall that leads into a hall of closets. Shaped like an oval, the room has a rainfall showerhead hidden in the ceiling. The toilet, bidet, and vanity are spread around. The flooring and walls are clad in creme Galala marble.

The unit is crowned with a 2,300-square-foot roof deck that has an outdoor kitchen with a soapstone counter, sink, refrigerator, and gas grill. All this is sheltered under a retractable cover. The deck also has a hot tub, a walk-in shower, and a reflecting pool.
