BUILDING COMPLETE. IMMEDIATE OCCUPANCY.

With views in all directions over the Upper West Side, the Penthouse at the Charlotte is a 4,042-square-foot four-bedroom, four-and-a-half-bathroom duplex with a 3,188-square foot landscaped private roof terrace and additional 853-square foot terrace off of the living and dining room. Architecturally gorgeous and without compromise in its quality and detail regarding sustainability, wellness, and design, the Charlotte of the Upper West Side sets a new standard of New York living.

An article in a September 2023 New York Times article raved that "Its airtight rooms use a fraction of the energy required by the buildings around it, staying cool in the summer and warm in the winter, while light-soaked and quiet."

Winner of the prestigious AlA Design Award for architectural excellence from the American Institute of Architects, the Charlotte was designed and engineered to meet the exacting certification criteria of the Passive House Institute, the state-of-the-art building boosts residents' well-bein and comfort with unmatched air quality, temperature control, sound attenuation, and daily convenience.

Robust insulation and airtight seals minimize air leaks and drafts, keeping rooms consistently comfortable and quiet while significantly reducing energy consumption and saving nearly 90% on heating and cooling bills. The multi-million-dollar energy recovery ventilation system exchanges each home's entire volume of indoor air with freshly UV-treated and filtered outdoor air every hour. The striking facade of iron-spotted terracotta louvers is designed to bring in sunlight during the winter and keep out heat during the summer.

A private elevator entry and gallery lead to the open great room with high ceilings and an art wall. Gallery-quality lighting is featured throughout. Guardian Ultra Clear museum-quality glass floor-to-ceiling windows--quadruple-layered yet operable--with acoustical lamination bring unparalleled light and sound attenuation. Wide-plank European white oak floors in a ladder pattern add charm and warmth.

In its own wing, the primary bedroom suite has a spacious walk-in closet, open views, and a south-facing balcony clad in Italian porcelain tiles. The primary bathroom showcases floor-to-ceiling marble slabs and radiant-heated floors.

The upper level is accessed by way of a graceful interior staircase. This level houses the penthouse's fourth bedroom which can also be used as a lounge. The room is surrounded by the 3,188-square-foot landscaped private roof terrace, with all of its options for entertaining, including a gas barbecue, and magnificent views.
