This iconic Tribeca penthouse is truly one-of-one, a sprawling five-bedroom, four-bathroom home of extraordinary character, crowned by a large private roof deck, barrel-vaulted ceilings, exposed brick, hardwood floors and an enormous skylight that pours daylight into the heart of the apartment. A dramatic corner living room anchors the entertaining level, where grand proportions are balanced by the warmth and texture of a true downtown loft. Central air conditioning and extraordinary closet space bring modern comfort to a home whose architecture remains unmistakably Tribeca.

At its center is a chef's kitchen designed for those who love to cook, with solid-wood cabinetry, Sub-Zero refrigerator and freezer, and a magnificent La Cornue range vented directly to the exterior. Upstairs, a private library creates an inspired home office, reading room or retreat before opening onto an enormous private roof deck, a rare expanse of outdoor space above the rooftops of one of Manhattan's most storied neighborhoods. It is the kind of place made for long summer dinners, morning coffee in the open air and evenings when the city itself becomes the backdrop.

The private bedroom level feels almost like a home unto itself, with a large den, dedicated laundry and an expansive owner's suite conceived as a true sanctuary. The suite pairs an enormous walk-in closet with a spa-like bath, while the secondary bedrooms are exceptionally generous and offer excellent storage of their own. The separation between entertaining, working and sleeping spaces gives the residence an ease that is exceedingly difficult to find in a downtown loft-particularly one of this scale and architectural distinction.

55 Hudson Street is an intimate boutique building offering a key-locked elevator, live-in superintendent and on-site storage, set in the very heart of Tribeca. Duane Park, Washington Market Park, Whole Foods and express subway lines are all close at hand, along with the restaurants, galleries and cobblestone streets that have made the neighborhood one of New York's most enduring addresses. Singular in scale, character and setting, this is more than a Tribeca penthouse. It is a once-in-a-generation opportunity to own an iconic downtown home
