Crowning a boutique elevator building, the residence blends industrial soul with cosmopolitan flair. The main living level is crafted for everyday comfort and dazzling entertaining. Soaring timber ceilings, exposed brick, and a dramatic wall of commercial-grade windows fill the space with natural light and frame city views. Expansive 3000 sq ft living and dining areas flow into a chef's kitchen appointed with two of everything: double Sub-Zero refrigerators, an oversized six-burner Viking range with Bertazzoni hood, a five-burner Viking range, Bosch and Viking dishwashers, two Kalista De Giulio sinks, Taj Mahal quartzite countertops, custom Ann Sacks and Fine Line tile, and fixtures from Sherle Wagner, Waterworks, and Dornbracht.
