The Alden (225 Central Park West)

Reflecting its apartment-hotel origins, the Alden's unit mix is broader than typical CPW landmarks: studios and one-bedrooms (originally hotel-residential units, many now combined) sit alongside substantial two-, three-, four-, and five-bedroom configurations including a number of combined and full-floor layouts.

Pre-war signatures throughout: high beamed ceilings, formal entry galleries in the larger configurations, gracious room proportions, Central Park views from the eastern-flank apartments. Original architectural detail is preserved to varying degrees apartment-to-apartment depending on renovation history.

Park-facing apartments occupy the eastern flank with direct Central Park views; corner Park-facing units (Park + West 82nd Street exposure) command meaningful view premium given the building's corner positioning.

The Alden operates as a full-service pre-war cooperative with the hospitality-influenced service signature appropriate to its apartment-hotel origins: 24-hour doormen, concierge desk, spectacular lobby, on-site superintendent. Recent capital reinvestment has refreshed the lobby and common areas while preserving the building's pre-war character. On-site amenities include a roof deck, garage, and bicycle room — broader amenity scope than most CPW pre-war co-ops of comparable era.

The building converted to cooperative ownership in 1984 and has operated continuously as a self-governed co-op since.

Policy flexibility distinguishes the Alden from peer CPW co-ops. The board permits:

• Pied-à-terre purchases (per building policy)
• Co-purchasing
• Pets (for shareholders; not permitted for subtenants)
• Subletting with board approval, on a tiered fee structure that escalates with sublet duration

The board does not permit guarantors or parents-buying-for-child(ren) arrangements, in either employed-child or student-child variants. These rules govern eligibility; they do not establish the actual size of the buyer pool or sales velocity.

Sublet fees are calibrated by year of sublet — approximately $9 per share per year for Year 1, escalating to $21 per share per year for Year 4 and beyond. This structure discourages indefinite subletting while accommodating shareholders with temporary need.

The building participates in the NYC Cooperative & Condominium Property Tax Abatement Program for qualifying primary-residence shareholders.

Property is managed by AKAM.

Recent transfers at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. $/sf is measured on the latest sales with reliable square footage (2023): a median $1,264/sf (recorded) across 1 sale. The building has traded as recently as 2026. Median listing discount 0.9% 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 1-01196-0029). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price.

Board approval is rigorous but the building's policies are notably flexible. Pied-à-terre, co-purchasing, and pets are all permitted — making the Alden one of the more accessible tier-one CPW addresses for buyers who don't fit traditional primary-residence-only profiles.

Confirm the guarantor policy. Whether the board accepts guarantors or co-purchasers is set by its application requirements; buyers who plan to rely on another party's financial support should confirm the policy before contract.

Studios and one-bedrooms are available at meaningful scale. Reflecting the building's apartment-hotel origins, smaller units are common — useful for buyers who want CPW architecture but don't need (or can't underwrite) a full pre-war family apartment.

Subletting is permitted with a tiered fee structure. The escalating per-share annual fees mean longer-duration subletting becomes progressively expensive — buyers planning to sublet should model the long-tail cost.

Renovation is constrained by historic district status and pre-war detail. Renovation respecting the building's Neo-Renaissance character is the expected path.

Views depend on the apartment. Central Park lies to the east, with residential streets surrounding; views vary by floor, position and exposure, and no view is protected without a recorded instrument.

Pricing spans a broader range than at most CPW co-ops. The unit-mix breadth — studios to multi-bedroom combined units — means seller pricing strategy benefits from broker familiarity with the building's specific inventory dynamics. Comparable-sales analysis is more useful at the Alden than at smaller, more variable buildings.

Explain the documented policy conditions. Pied-à-terre, co-purchasing and shareholder-pet permissions may suit particular buyers; confirm the current terms and subtenant restrictions. These permissions do not establish a broader buyer pool or faster average transactions than nearby cooperatives.

Mansion tax effects depend on apartment scale. Studios and one-bedrooms typically trade below the mansion tax thresholds; larger configurations routinely transact above $2M and not infrequently above $5M.
