According to a recent LinkedIn post from SERHANT Technologies, the firm is marketing a high-end penthouse, Penthouse B at 655 Sixth Avenue in Manhattan’s Chelsea neighborhood, with an asking price of $13.495 million. The residence is described as a grand duplex within the landmarked O’Neill Building, combining historic cast iron architecture with contemporary luxury design features.

The post highlights attributes such as more than 4,800 square feet of interior space, over 2,500 square feet of private outdoor area, a 53 foot Great Room with extensive window frontage, and a gold coated Neo Grec cupola that can function as a media room or office. It also references multiple terraces, a secluded primary suite level, and full-service condominium amenities, with brokerage representation noted for an individual agent.
For investors, the marketing of a property at this price point suggests SERHANT Technologies continues to target the upper tier of the New York City residential market, where individual transactions can contribute meaningfully to brokerage revenue. The emphasis on architectural pedigree, expansive outdoor space, and unique features such as the cupola may indicate a focus on differentiated inventory that can command premium commissions.
The post also implies ongoing activity in the Chelsea luxury segment, a market sensitive to broader conditions in high-end urban real estate, including interest rates and global wealth trends. Successful sale of this property at or near the listing price would support the company’s positioning in the luxury brokerage and proptech ecosystem, potentially enhancing brand visibility among affluent buyers and sellers.
