The Charles is a 31–32 story full-service condominium tower completed in 2015 on Manhattan’s Upper East Side, conceived by Ismael Leyva Architects with interiors by David Collins Studio. The building’s composition is unusually residential: mostly full-floor four-bedroom homes plus a single duplex penthouse, each reached from a private elevator landing and supported by a separate service entry for deliveries and staff circulation. Residences feature high ceilings (often 10'–12'), floor-to-ceiling glazing on multiple exposures, wide-plank white oak flooring, custom millwork, and systems pre-wiring for home automation and whole-home audio. Kitchens are specified with Corian surfaces and top-tier Sub‑Zero and Miele appliances; primary baths use Calacatta/Italian marbles and high-end fittings. Common areas reflect a boutique, white-glove stance: a 24-hour attended lobby with a live-in resident manager, package and refrigerated storage, private storage cages for owners, and a children’s playroom. The fitness center (Technogym/Peloton equipment) occupies above-ground space and is part of the building’s wellness offerings. Exterior amenities include a planted garden and on-site storage; the property is pet friendly. The building emphasizes privacy, quiet (soundproofing and radiant/heated flooring in select areas), and full-floor proportions that cater to family-scale living amidst the Upper East Side’s cultural and transit connections.
