Offered together, Penthouse A and Penthouse B provide a rare full-floor presence and the opportunity to seamlessly combine two exceptional homes into a bespoke 4+ bedroom penthouse oasis, crowned by expansive wraparound terraces with breathtaking 360-degree skyline views, subject to review by the purchaser’s architect and Board approval. Rarely does a residence of this scale become available, offering the coveted combination of full-floor privacy, exceptional outdoor living, and panoramic exposures in one of Chelsea’s most iconic prewar buildings. The combined offering allows for the creation of a grand-scale home that is both elegant and highly functional, with the privacy and exclusivity typically reserved for the city’s finest penthouses. Alternatively, the residences may remain separate, preserving two beautifully appointed two-bedroom, two-bathroom penthouses ideal for guests, extended family, live-work flexibility, or any lifestyle that benefits from privacy while maintaining close connection. Designed by the renowned architectural firm Farrar & Watmough and completed in 1930, London Terrace Towers stands among Chelsea’s most distinguished prewar cooperatives. Residents enjoy an exceptional collection of amenities, including a state-of-the-art fitness center, heated indoor swimming pool, sauna, steam room, beautifully landscaped private gardens, rooftop deck, bicycle storage, laundry facilities, and an on-site parking garage. Perfectly positioned alongside the High Line and moments from Chelsea’s celebrated galleries, acclaimed dining destinations, cultural institutions, and vibrant theater scene, this remarkable offering presents a rare opportunity to craft a trophy penthouse residence defined by iconic views, expansive outdoor living, full-floor privacy, architectural pedigree, and limitless potential. Penthouse A is available exclusively in conjunction with Penthouse B and is not being offered separately. ## Property Details - **Property Type**: Co-op - **Beds**: 4 - **Total Baths**: 5 - **Rooms**: 9 - **Stories**: 18 - **Year Built**: 1930 - **Common Charges**: $14,736 / Monthly - **Listed On**: Jun 26, 2026 - **Days on Market**: 102 Days ### Residence Features - Central Air - Common On Floor - Common Area - In Unit - Garage - Building Roof Deck - Private Outdoor Space Over 60 Sqft - Entrance Foyer - Dryer - Dishwasher - Washer - Hardwood - Security System - City - Skyline ### Building Amenities - Sauna - Garage ## Estimated Monthly Payment **$79,965 / month**, assuming a 20% down payment ($2,580,000), a 6.5% interest rate and a 30-year term.

Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below. ### How this price compares - **This home**: $12,900,000 - **Median sold price**: $2,999,999 - **Difference**: +$9,900,001 (+330%) - **Comparable sales**: 3 - **Sales from**: September 2025 – March 2026 - **Middle half of those sales**: $2,432,500 – $4,300,000 Based on co-op four-bedroom sales in Chelsea. Square footage is recorded for only 2 of these 3 sales (67%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest. This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Chelsea instead. ### How these sales were negotiated - **Sale-to-list price**: 93.4% (3 sales) - **Sold below asking**: 100% (3 sales) - **Typical time to find a buyer**: 42 days (3 sales) - **Typical time to close**: 81 days (3 sales) Based on co-op four-bedroom sales in Chelsea with the required listing and closing data. Sample sizes vary by metric. These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure. Sales data through June 2026. Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.
