Dag Hammarskjold Tower

The tower is a well-proportioned early-1980s design, its slab massing relieved by a chamfered corner at 47th Street incised with a vertical center groove — a small piece of detailing that gives the building a recognizable profile on the Second Avenue skyline. The masonry-and-window elevation is straightforward and durable, built for light and the views the height delivers rather than for ornament.

The 229 residences span studios through larger two- and three-bedroom layouts, with the floor plans and exposures varying widely across a 43-story tower. Height and orientation are the levers of value: the upper-floor units with East River, UN, and skyline outlooks command the building's premium, while lower and side-facing homes offer the same full-service building and amenity floor at gentler numbers. Many residences have been renovated over the building's four decades, so condition varies meaningfully across lines.

Dag Hammarskjold Tower runs as a full-service condominium. A 24-hour doorman and concierge, a resident manager, and a service staff support the building. The amenity floor is the building's calling card — a rooftop heated indoor swimming pool, a fitness center, and a landscaped terrace — joined by a children's playroom, bicycle storage, and an on-site parking garage, an unusually deep package for a Turtle Bay building.

As a condominium, financing is flexible and not subject to the strict caps common at East Side co-ops, and pied-à-terre ownership, subletting, and purchases through trusts or LLCs are permitted under the bylaws — the ownership freedom that draws investors, diplomats and UN-affiliated buyers, and second-home purchasers to the building. Pets are welcome, subject to the house rules.

Recent sales

Market read. Most recent trades (2026) cleared a median $1,197/sf across 3 sales. Median listing discount 4.7% 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 1-01320-7501) 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 from recorded condo declarations and offering plans.

Buy here for the rare Turtle Bay combination: a true high-rise condominium, a rooftop pool and fitness floor, an on-site garage, and big views — all with condominium flexibility rather than a co-op board. The purchase process is lighter than a co-op's, clearing through a right-of-first-refusal in place of a board package and interview, with flexible financing and the freedom to sublet or hold as a pied-à-terre.

Within the building, floor and exposure decide value. The high east-facing lines with the East River and UN outlook are the building's signature product; west and south exposures trade the river view for the Midtown skyline at different price points. Because the building turns over often, a target unit can be benchmarked directly against recent sales of the same line — we help read those comps and assess renovation condition, which varies widely across a tower now more than forty years old.

The selling case is strong: a full-service condominium high-rise with a rooftop pool, a garage, and commanding views, two blocks from the United Nations — at a price well below the Park and Fifth Avenue tier. The buyer pool is broad and includes UN- and diplomat-affiliated purchasers, investors drawn by the permissive sublet posture, and trade-up owners who want condo flexibility.

Two levers drive the achievable price. First, the view — a high east-facing line with the river and UN outlook is a different (and higher) product than a lower interior unit, and the listing should lead with whatever the residence actually sees. Second, condition — in a 1982 building, an updated kitchen and bath materially shorten time on market. Frequent internal turnover gives a clear, defensible comp set, and a condominium resale clears through a right-of-first-refusal rather than a co-op board — a faster, more predictable close that is itself a selling point.
