Two Waterline Square is the largest of the three towers at Waterline Square, and the one where the development's basic bargain is clearest: a KPF tower on a Hudson-facing parcel, 160 condominium residences stacked above 486 rentals, all of it sitting on a 100,000-square-foot shared amenity club and a 2.6-acre park — with a 421-a abatement running to 2039 underneath the whole thing.
The site is the last piece of Riverside South, the decades-long redevelopment of the 77-acre Penn Central rail yard between West 59th and West 72nd Streets. Donald Trump assembled the land in 1974; it passed through Hong Kong investors, then to Extell Development and the Carlyle Group in 2009 for $1.76 billion, and finally to GID Development Group, which bought the Riverside Center parcel from Extell in 2015 for $676 million. GID secured $1.243 billion in construction financing in November 2016 — among the largest construction loans in New York City history at the time — and delivered the three towers between 2019 and 2020.
What distinguishes Waterline Square from the Costas Kondylis towers that make up the rest of Riverside South — 100, 120, 200, 220, 240 Riverside Boulevard, and The Rushmore at 80 — is that GID commissioned three different architects and three different interior designers under a Christian de Portzamparc master plan, then bound them together with a single shared amenity base. Two Waterline Square is the Kohn Pedersen Fox tower, with interiors by Yabu Pushelberg. It is the largest of the three and the most conventionally residential in its massing: a rectilinear curtain-wall slab on the northeast of the parcel, oriented to produce corner exposures on most lines and Hudson sightlines from the west-facing inventory.
The structure worth understanding is the condominium-over-rental stack. The tower holds 646 residential units; 160 of them were offered as condominiums, and they begin at the 20th floor. The 486 apartments below are rentals, with a separate entrance and separate elevator core. This is not unusual in new Manhattan development, but it has three practical consequences for a condominium buyer here. First, every condominium residence is a high-floor residence — the 20th floor is the base of the offering, not the middle of it. Second, the condominium is a minority of the building by unit count, which shapes how shared operating costs and reserves are allocated between the condominium and the rental owner. Third, the building's day-to-day character is set by a resident population several times the size of the condominium itself.
The amenity package is the marketing engine and, honestly assessed, the reason many buyers choose Waterline Square over the Kondylis towers up the boulevard. The Waterline Club is a Rockwell Group design across three below-grade levels and roughly 100,000 square feet, shared by all three towers: an indoor tennis court and a skate ramp, both firsts in a New York residential building; a squash court; a 30-foot climbing wall; an indoor soccer pitch; a 25-meter lap pool and a children's pool; a two-lane bowling alley; a recording studio; a gardening studio. Above it sits Waterline Square Park, 2.6 acres by Mathews Nielsen. At the base, Harry's Table by Cipriani opened as a 28,000-square-foot food market in 2022.
And underneath all of it: the 421-a abatement, running to 2039. For a buyer comparing Two Waterline Square against the older Riverside South condominiums — most of which have run out their abatements — the effective monthly carrying cost differential is large, durable, and the first thing that should be modeled.
Architecture and unit composition
KPF's tower is the least gestural of the three at Waterline Square and, for most buyers, the most livable. Where Richard Meier's One Waterline Square is white-panel modernism and Rafael Viñoly's Three Waterline Square is the sculptural one, Two Waterline Square is a straightforward high-performance curtain wall organized around getting light and corners into as many apartments as possible.
The 160 condominium residences run one through four bedrooms across floors 20 to 38. Yabu Pushelberg's interiors favor organic materials and long sightlines against the floor-to-ceiling glazing; kitchens carry Gaggenau appliance suites, with Dornbracht and Valli & Valli fittings throughout. Exposure is the dominant pricing variable: west-facing inventory carries Hudson River and sunset outlook, north- and east-facing inventory carries city and park views over the Waterline Square Park, and the premium between them is meaningful on every floor.
Building operations
Two Waterline Square is a full-service condominium inside a larger mixed-tenure building inside a larger three-tower development. That layering is the operational story, and it generates the diligence list.
The condominium is one of several parties to a shared-amenity structure. The Waterline Club serves all three towers and both tenures. Ask how the condominium's share of amenity operating cost and capital reserve is calculated, and what the condominium's governance rights are over that budget. This is normal for a master-planned development and it is where the surprises live.
The rental component sits below the condominium in the same tower. Understand the cost-sharing allocation between the condominium and the rental owner for the shared building systems, façade and elevators, and whether the condominium board has any say over rental-side capital decisions that affect shared elements.
The 421-a abatement phases out. An abatement running to 2039 is a genuine asset, but it steps down over its final years and the unabated tax at the end is the number that determines the long-run carrying cost. Model both the current bill and the fully unabated bill on the specific unit before deciding what the apartment is worth.
The building is young enough that the capital history is short. Ask for the audited financial statements, the reserve balance, and any sponsor-turnover punch-list items still outstanding — 2019-2020 vintage towers are now far enough past delivery that early construction issues, if any, have surfaced.

What to know if you’re buying
Model the abatement, both ends of it. Current bill and fully unabated bill. The 2039 runway is real value; the step-down is real cost. Both belong in the model.
Buy the exposure. The Hudson-facing lines are the reason to be in this building rather than in a comparable amenity tower elsewhere on the West Side.
Read the shared-amenity documents. A 100,000-square-foot club shared across three towers and two tenures has a cost allocation, a governance structure and a capital plan. Get all three.
Understand the condominium-over-rental structure. It is not a defect and it is common in this generation of Manhattan development, but it changes the governance and cost-sharing picture relative to a wholly owned condominium tower.
Location trade-off is real. Riverside South is Hudson-adjacent, park-adjacent and quiet, and it is a walk from the subway. The 59th Street–Columbus Circle station (1, A, B, C, D) is the nearest, and it is not close. Buyers who prioritize transit density should weigh that honestly.
What to know if you’re selling
Lead with carrying cost, not price. The abatement is your strongest argument against every unabated comparable in Riverside South and Lincoln Square. Present it as a monthly number.
Lead with the amenity club. It is the most distinctive residential amenity package on the West Side, and it is verifiable rather than promotional.
Price by line and exposure. Building averages are misleading in a tower where the west-facing and east-facing lines are effectively different products.
Cross-shop the buyer against the older boulevard stock explicitly. Most buyers arrive comparing you to 100, 120 and 220 Riverside Boulevard. Make the carrying-cost comparison for them.
