In late July 2026, New York’s Flatiron Building was completing a seven-year renovation that would turn the former office tower into 36 ultra-luxury condominiums, with top-end units priced at $58.5 million. The work included a full façade refurbishment, energy-efficient windows, and the reconstruction of historic interior features, such as a 20th-floor balcony. The project, led by the Brodsky Organization following a $161 million auction in 2023, features amenities including an 18-metre pool, wellness centre, billiard room, and piano lounge. 

By mid-August 2026, the residential conversion showed significant momentum, reaching an 82% absorption rate with 18 of 22 residences listed on StreetEasy already sold. This rapid sales pace has placed the building at the top of luxury contract reports. The renovated exterior was expected to be fully revealed by the end of summer 2026, with unit hand-over and the full amenity package slated for early 2027.

Parallel to the New York project, the historic Friedrichstraße 210 building at Checkpoint Charlie in Berlin is being converted into 20 serviced apartments. Leased to Urban Flats Berlin for a 15-year term, the project will offer 27 short-term bedrooms across two floors and is scheduled for completion in the second quarter of 2027, underscoring a growing trend of repurposing iconic historic structures for premium residential use.
