430 West 34th Street (Convention Overlook)

The building runs 17 floors and approximately 178 apartments per city records, configured almost entirely as straight studios, alcove studios, and one-bedrooms, with a small number of terraced units, garden-level lines, and penthouses. Layouts are classic Feldman-era efficiency: defined entry foyers, pass-through or enclosed kitchens, and generous closet runs for the size class. Select lines carry private terraces or garden frontage that are unusual at this price point — listing records have documented one-bedrooms with 20-foot-plus terraces and planted garden extensions. Upper-floor units on the south face look toward the Hudson Yards towers and Javits; north-facing lines look into the Hell's Kitchen mid-blocks.

Full-service for its tier: 24-hour doorman, live-in superintendent, porter staff, central laundry, storage, and bike room. The lobby was renovated in 2005 and listing records document a fresh lobby and hallway renovation cycle completed in 2025. Maintenance is repeatedly characterized in listing records as low for a doorman building, with heat, hot water, and gas bundled — a meaningful line item when comparing against the corridor's condo carrying costs. The offering plan and amendments are on file in The Roebling Research Library; current financials should be reviewed by counsel during diligence.

Recent sales

Recent transfers at this building, curated by The Roebling Team research desk. Apartment-level facts are independently verified before publishing; sale prices reflect the recorded transfer amount at the NYC Department of Finance.

Market read. Most recent trades (2026) cleared a median $927/sf across 1 sale. Median listing discount 2.7% 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 1-00731-0060) 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.

You are buying the location's future at the location's past pricing. The block's infrastructure — the 7 at Hudson Yards, the A/C/E at Eighth Avenue, Moynihan Train Hall, the High Line entrance, Hudson Yards and Manhattan West retail — is fully delivered, and this building's pricing has not converged with it. The value case is structural, not speculative.

Calibrate expectations on the block itself. West 34th Street between Ninth and Tenth is a working crosstown corridor: Javits event traffic, Lincoln Tunnel approaches, and Penn Station flows are all real. Spend time on the block at rush hour and on an event day before offering.

The policy framework is unusually flexible for a co-op. Pets, pieds-à-terre, co-purchasing, gifting, and guarantors are all documented as permitted, and the sublet posture is liberal by co-op standards — which supports both investors and parents buying for children. Verify current sublet terms directly, as records conflict on the details. Run the Co-op Board Qualification Calculator before offering.

Underwrite the maintenance bundle. Heat, hot water, and gas inside the maintenance changes the monthly math against condos that bill everything separately. Run the True Monthly Carrying Cost Calculator on a true apples-to-apples basis.

Verify the fee stack at offer stage. Flip tax, financing maximum, and current sublet fees are thinly documented publicly. We verify against the offering plan and amendments on file, and the managing agent, during diligence.

Sell the corridor, not the brick. Your buyer pool is priced out of the Hudson Yards condos but wants the same map. The marketing should lead with transit, the High Line, Manhattan West, and the roof deck's skyline frame — the building's 1963 envelope is the discount mechanism, not the headline.

The investor-flexible policies widen your exit. A sublet-friendly, pied-à-terre-friendly co-op clears to a deeper pool than a primary-residence-only building. Make the policy framework explicit in the listing; many co-op buyers assume the opposite by default.

Price to the line, and to condition. The spread between renovated terraced lines and estate-condition studios is wide in percentage terms at this price point. Run the Renovation Cost Calculator against your asking strategy before listing.
