31 East 28th Street is a boutique full-service condominium in NoMad — the district north of Madison Square Park that has become one of Manhattan's most sought-after central neighborhoods over the past two decades. The building was constructed in 1913 as a commercial structure during the Beaux-Arts build-out of the blocks around Madison Square, and was converted to residential condominium use in 2006, with interiors by designer Alan Tanksley. Today it holds 21 apartments across 12 floors.
The building represents a specific and desirable proposition: a prewar Beaux-Arts shell, reworked at conversion into a boutique condominium with full-service touches, in a NoMad location that pairs central convenience with genuine neighborhood character. NoMad's transformation — anchored by hotels, restaurants, and a dense, walkable street life — has made addresses like this one increasingly central to downtown-leaning buyers who want to be near Madison Square Park, the Flatiron and NoMad dining scene, and the city's principal transit lines.
For buyers, 31 East 28th Street offers what the boutique converted condominium does best: prewar architectural character and contemporary, post-conversion systems and finishes, in the flexible condominium ownership structure, at a building scale small enough to feel personal rather than institutional.
Architecture and unit composition
The original 1913 building is a Beaux-Arts–era commercial structure — the period's masonry-and-ornament vocabulary applied to a Madison Square commercial block. The 2006 conversion reworked the building into a residential condominium with interiors by Alan Tanksley, introducing the contemporary systems, kitchens, and bathrooms that distinguish a high-quality conversion from a raw loft. The original architect of record is not firmly documented in public sources; buyers who care about attribution should confirm against building filings.
In residential use, the building delivers the converted-prewar combination buyers prize: the volume, window lines, and character of the original structure, paired with the finishes and infrastructure of a 2006 renovation. With 21 units across 12 floors, the building runs to roughly one to two homes per floor — boutique density supporting larger, lower-density apartments. Configurations include the larger two-bedroom and penthouse-tier homes characteristic of high-end NoMad conversions.
Apartment-level features — floor, exposure, light, ceiling height, square footage, and the specific finish package — vary unit by unit and are the primary drivers of value. Evaluate each home on its specific configuration.
Building operations
31 East 28th Street operates as a full-service boutique condominium, with doorman/concierge service reported as part of the building's program. Common charges support building services and staffing, with governance through the condominium's board of managers and by-laws.
Specific amenities, staffing levels, and policies on pets and alterations are set in the offering plan and the condominium's governing documents. Because condominium use permits broad financing, pied-à-terre, and investment flexibility, the building accommodates a wide range of ownership cases. Prospective buyers should confirm the current rules, the building's financial profile, the common-charge and assessment history, and the status of building systems directly against current materials during due diligence; board specifics should be confirmed at offer stage.
Recent sales
Sales at 31 East 28th Street are best read on a condominium basis — on price per square foot and on apartment-specific configuration. The building sits in the upper-mid tier of NoMad boutique condo pricing, reflecting the full-service profile, the quality of the 2006 conversion, and the strength of the NoMad location. Larger two-bedroom and penthouse-tier homes carry the building's higher prices; smaller units price below.
Value tracks the usual condo variables — floor, exposure, light, ceiling height, square footage, layout, and finish condition — with the converted-prewar premium attaching to homes that pair genuine character with strong post-conversion finishes. Because the building is small, in-building comparable sales are episodic; pricing any individual apartment requires reading both in-building history and the broader NoMad boutique condo market. Recent specific transactions should be confirmed against current public records at the time of any inquiry.

What to know if you’re buying
This is a converted prewar condominium — underwrite both the shell and the conversion. Value tracks square footage, ceiling height, light, and the quality and age of the 2006 finishes and systems. Confirm as-built square footage and layout, and price per square foot against comparable NoMad condos.
Condominium flexibility is a real advantage. The structure supports higher financing percentages, pied-à-terre and investment use, and a faster, less selective approval process than a comparable cooperative. Our Co-op vs Condo guide covers the distinction.
Diligence the building's finances and systems age. Review the common-charge history, the reserve position, any assessments, and the status of building systems — even a 2006 conversion is now approaching two decades of service life on its post-conversion mechanicals.
NoMad is central and lively. The location pairs Madison Square Park proximity and excellent transit with a dense restaurant and hotel district. Visit at multiple times to confirm fit.
Closing timelines are condominium-standard. Plan for 45–60 days from contract through closing under typical financing and due diligence circumstances.
What to know if you’re selling
Lead with the full-service profile and the NoMad location. The building's structural selling points are the converted-prewar character, the full-service touches, and a genuine NoMad address. Apartment-specific marketing should foreground the home's exposure, light, square footage, and finish condition.
Price on apartment-level comparables. With a small in-building sample, anchor pricing to recent comparable NoMad condo sales in the building and across the district on a per-square-foot basis.
Board approvability is procedural. The condominium's review of prospective purchasers is procedural rather than substantive, which broadens the buyer pool relative to a comparable co-op.
