212 East 48th Street

Duncan's design is classic 1920s apartment architecture — a dark-red-brick facade rising nine stories from a one-story stone base, articulated with an entrance marquee and a nicely scaled cornice. It is restrained and well-proportioned, the work of an architect who built civic monuments and brought that sense of order to a residential block.

Inside, the cooperative comprises roughly four dozen apartments across the nine floors — a mid-density building where layouts reflect the prewar planning of generous foyers, separated rooms, and the room-by-room logic of the era rather than open-plan modernism. The marble-and-arched-glass lobby sets the tone, and the private garden and landscaped roof deck extend the living space outdoors.

212 East 48th runs as a full-service prewar cooperative. A 24-hour doorman staffs the lobby, a live-in superintendent handles building needs, and residents have a central laundry, a private garden, and a landscaped roof deck. The full-time staffing and outdoor amenities are a real draw at this scale and price point.

As a cooperative, the building reviews purchasers through a board package and interview, and the board sets policy on financing, subletting, and pied-à-terre use. Here the posture is relatively accommodating for a prewar co-op: co-purchasing, pied-à-terre use, pets, and subletting (after a holding period of roughly two years) are permitted with board approval. Buyers and sellers should confirm the current financing cap, sublet terms, and any flip tax through the building's house rules and managing agent as part of a transaction.

Market read. Most recent trades (2026) cleared a median $682/sf across 1 sale. Median listing discount 1.7% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01321-0042) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.

This is a cooperative, so plan for the co-op process: a board package, an interview, and board-set rules on financing, subletting, and pied-à-terre use. The good news is a comparatively flexible posture — co-purchasing, pied-à-terre, pets, and post-holding-period subletting are permitted with board approval. Confirm the financing cap and the exact sublet holding period before you bid. The reward is full-time staffing, a garden, a roof deck, and prewar construction steps from Grand Central — strong value in the Midtown East prewar market.

Lead with the staffing and the outdoor space. A 24-hour doorman, a private garden, and a landscaped roof deck are an unusually deep package for a building of this size and price, and the marble-and-arched-glass lobby makes a strong first impression. Benchmark to the Turtle Bay prewar co-op segment, where prewar layout, light, and full service drive value. The building's relatively flexible board policy is a selling point — be ready to articulate the financing and sublet posture, since buyers will weigh it early. The Grand Central, UN, and subway proximity anchors the location pitch.
