Rendering of a penthouse at 20 East End Avenue via Curbed.

The market for luxury new construction condos is thriving in NYC, and as a result, Manhattan’s neighborhoods have maintained their distinct styles while keeping a modern edge.

Just last week, we caught a glimpse of the penthouse renderings in the Robert A.M. Stern–designed project, 20 East End Avenue in the Upper East Side. These designs perfectly line up with . Herringbone-pattern floors, crown and floor molding details, and even functional fireplaces are in store for their future residents. Noticeably, floor plans indicate open concept kitchens, conferring a decidedly modern convenience. Both penthouses are 5-bedroom, 5.5-bath homes that span over 6,000 sqft, but the first of them has the exclusive benefit of four rooftop terraces. As a whole, 20 East End Avenue reinterprets classic Manhattan for the modern day, implementing features like a porte-cochere.

Going the aesthetically opposite way — not to mention geographically opposite, being cater-cornered from the UES in Soho — 10 Sullivan Street is just about complete. Billed as the tallest residential building in Soho, this flatiron-shaped building is sure to offer astounding views of Downtown Manhattan from its semicircular windows. with the same level of detail and context-awareness as his other buildings in Lower Manhattan, which include 456 West Street and 508 West 24th Street. A spacious triplex penthouse takes the topmost floors of 10 Sullivan Street, offering great views and more than 8,000 sqft, all at the price of a cool $45 million. To be sure, each of 10 Sullivan Street’s homes feature hallmarks of loft-style luxury, like extraordinarily high ceilings and oversized, gridded windows; but they also promise to make excellent use of elite materials, such as Danish oak and Dolomite marble.
