LISTING DETAILS FOR East 21st Street Condo Office for Sale

DESCRIPTION

Positioned on one of Flatiron’s most architecturally distinguished blocks, the entire second floor at 25 East 21st Street represents a rare opportunity to own or occupy one of the most refined full-floor office condominiums in Midtown South. Designed for creative, financial, and professional users who prioritize light, scale, and control over their working environment, this immaculate floor combines a generous open plan with defined private zones, high ceilings, and the elegance of prewar proportions married to a modern build-out. With four windowed private offices, three fully enclosed conference rooms, and a sweeping open bullpen accommodating thirty or more workstations, the layout balances collaboration, privacy, and client-facing sophistication in a way that few downtown spaces can replicate.

Accessed by a direct keyed elevator that opens into a private reception foyer, the arrival sequence immediately communicates exclusivity and polish. The main workspace extends southward, framed by plaster-finished thirteen-foot ceilings and a series of grand picture windows that wash the space in natural daylight. Along the perimeter, four large glass-fronted offices line the southern wall, each enjoying full exposure and skyline sightlines. These rooms are ideal for executives, partners, or senior creative staff—large enough to function as individual suites yet transparent enough to maintain visual connection with the broader team. Between them, three conference rooms of varying scale offer flexible meeting environments: a formal boardroom for twelve, a midsize team room, and a smaller breakout or client-presentation space. Each is fitted with integrated audiovisual wiring and contemporary lighting, ensuring the space is as functional as it is beautiful.

At the heart of the layout, a broad open bullpen serves as the operational engine of the office, capable of housing over thirty workstations without feeling dense or cluttered. The column-free configuration, spanning nearly forty-four feet across, creates an uninterrupted field of space conducive to teamwork and adaptability. Toward the interior core, a newly constructed stainless-steel pantry with full-size appliances provides a hospitality-grade amenity for daily use or client entertaining. Adjacent to it are two newly built restrooms, a dedicated IT/server closet, and several auxiliary storage rooms—features often overlooked in lesser installations but essential for long-term usability.

Every detail of the build-out was executed to a standard well above the market norm. Finishes include fine plaster ceilings, recessed LED track lighting, and tailored millwork that highlights the building’s prewar character while keeping the aesthetic crisp and current. The combination of wide floor spans, southern light, and refined materials produces an atmosphere that feels equal parts gallery, studio, and headquarters. Office furniture is available as part of a turnkey offering, making immediate occupancy effortless for a buyer or user who values time and presentation equally.

Beyond the suite itself, ownership at 25 East 21st Street carries the advantage of being in one of Flatiron’s most desirable boutique office properties—an address known for its architectural integrity, discreet prestige, and impeccable maintenance. The building’s recently renovated attended lobby greets visitors with hospitality-level professionalism, and its proximity to both Union Square and Madison Square Park situates tenants at the nexus of Manhattan’s creative and corporate energy. Surrounded by acclaimed restaurants, cafés, fitness studios, and transit access via the 6, N, R, Q, and W lines, the location supports an ideal balance between work and lifestyle.

Few spaces combine ownership opportunity, design pedigree, and day-to-day functionality at this level. The full-floor commercial condominium at 25 East 21st Street delivers an immediate, tangible sense of quality—an environment where architecture, light, and layout align perfectly for firms ready to make a long-term investment in both space and identity.
