Inside The Harper: A Rare Upper East Side Gem Redefining Luxury Living in Manhattan

On June 26th in Manhattan, The Harper opened its rooftop to guests for an elegant summer soirée—a toast to the season and a closer look at one of the Upper East Side’s most compelling new luxury offerings. Held on the private roofdeck of Penthouse B, the celebration featured live entertainment, fine wine, and hors d'oeuvres—all set against a backdrop of sweeping city views. But while the occasion was a festive nod to summer, the real star was the building itself.

Located at 310 East 86th Street, The Harper is a newly completed 21-story, ground-up condominium development by IGI USA. Designed by the renowned architecture firm ODA, the building commands attention with its striking limestone façade, bold stepped geometry, and Art Deco-inspired brass accents. In a city defined by reinvention, The Harper manages to look both timeless and entirely of-the-moment.

Comprised of 63 residences ranging from two to four bedrooms, pricing begins at $2.2 million for a two-bedroom, with immediate occupancy available.

Inside, residences are designed to feel spacious and serene, with wide-plank European white oak flooring and oversized windows that flood the interiors with natural light. Poliform cabinetry, Miele appliances, and a curated palette of finishes—Taj Mahal quartzite, Namibia White marble, and Crema Luna limestone—offer a sense of effortless sophistication.

The architectural vision extends beyond interiors. More than 70% of homes include private outdoor space, a rarity in Manhattan—be it a terrace, balcony, or backyard. For those seeking the pinnacle of privacy, two penthouses feature full rooftop spaces and Jacuzzis. One of these has already sold, while Penthouse B, where the summer soirée took place, remains on the market for $7.4 million.

In line with IGI USA’s philosophy of creating amenity-driven residences, The Harper delivers a roster of offerings tailored to today’s luxury buyer. Residents are welcomed through a 24/7 attended lobby and have access to two landscaped rooftop terraces with panoramic views of the city and nearby parks.

Amenities are thoughtfully designed to cater to both relaxation and creativity. The on-site fitness center offers a private space to recharge, while a music studio and recording room—featuring programming from School of Rock—caters to budding musicians. For families, the building includes a children’s art and maker studio with sessions led by Robofun, as well as a vibrant playroom.

Entertainment and leisure are elevated with a game and screening lounge outfitted with a pool table, ping-pong, arcade games, and gaming consoles. A pet spa, bike storage, and additional conveniences round out the experience, balancing sophistication with functionality.

The Harper’s location places it within easy reach of both Central Park and Carl Schurz Park, offering residents access to expansive green space—a true luxury in New York. The neighborhood itself is anchored by enduring favorites like Elio’s, Campagnola, and the elegant Mark Hotel, reinforcing the Upper East Side’s reputation for refined culture, cuisine, and community.

With sales and marketing exclusively managed by CORE, The Harper stands as a meticulously designed answer to the evolving expectations of luxury real estate buyers in Manhattan. Its mix of architectural distinction, premium finishes, and lifestyle-forward amenities signals more than just another high-end address—it offers a genuine sense of place in a city always on the move.
