Description

Welcome to Loft 4B at The Foundry—a fully furnished studio loft offering a rare combination of style, serenity and turnkey condition. Tucked away at the quiet rear of the building, this residence provides a peaceful oasis in the heart of downtown Manhattan. The Foundry is a condop that permits unlimited subletting after one year of ownership. Step inside to oversized windows, newly installed 7.5” European white oak wire-brushed engineered hardwood and soaring 10’2” ceilings that create a bright, expansive atmosphere. The tranquil rear exposure enhances the sense of calm, making this home ideal for inspired work-from-home days and relaxed evenings. A thoughtfully designed lofted home office and sleeping area adds architectural interest and volume, comfortably accommodating a queen or full-size mattress while maintaining an open, airy living space below. Storage is seamlessly integrated with two generous hallway closets, offering excellent functionality without compromising style. The newly renovated kitchen is designed for everyday ease, featuring abundant cabinetry, a newly installed gas range, and a dishwasher. A recently upgraded bathroom completes the home with a clean, modern aesthetic. Set within The Foundry, a character-rich pre-war building converted from a historic factory, residents enjoy a curated suite of amenities including a beautifully furnished rooftop with a barbecue grill, on-site laundry, elevator access, and secure bike storage. Located just a couple of blocks from the subway, with a crosstown bus at your doorstep, you’re moments from Gramercy Park, Stuyvesant Square Park, the Madison Square Park, Flatiron District, East Village, NoMad, and some of downtown Manhattan’s most celebrated dining, shopping, and cultural destinations.

Gramercy Park is one of New York City’s most storied and picturesque neighborhoods, centered around the only private park in Manhattan. The area exudes old-world charm with its gas-lit streets and impeccably preserved 19th-century architecture. While the park itself is private, the surrounding real estate offers a mix of historic brownstones, elegant pre-war cooperatives, and boutique new developments that cater to those seeking a tranquil urban retreat.
