The signed contract at 105–107 Bank Street, first reported by The Wall Street Journal, positions this as the most expensive residential sale ever recorded in downtown Manhattan. The combined townhouse, a gut renovation by Robert A.M. Stern Architects, spans approximately 13,000 square feet across six floors.
RoundSquare Development acquired the two properties separately in 2021 and 2022 for a combined $18 million. The firm retained Robert A.M. Stern Architects for a comprehensive renovation that fused the adjacent structures into a single 40-foot-wide residence while preserving the original Federal-era facades.
At the rear of 105 Bank Street, a cast-iron spiral staircase connects the parlor floor to the garden. The staircase dates to the early 1970s, when the top floor was rented by John Lennon and Yoko Ono as their first New York City residence. The neighboring townhouse at 107 Bank Street was once home to composer John Cage and choreographer Merce Cunningham.
The property includes six bedrooms, a private elevator, a basement-level gymnasium and screening room, and multiple outdoor spaces including a terrace off the primary suite. It was listed at $75 million in October 2025 and entered contract at over $70 million in March 2026.
