Since launching sales only four months ago, Tamarkin Co. is celebrating the "topping out" of its new condominium building, 456 West 19th St. The 11-story building is located in the heart of West Chelsea's art gallery district. "We're thrilled to have reached this milestone and are looking forward to having residents move in early next year," said the building's architect and developer, Cary Tamarkin. "456 West 19th Street is truly a one-of-a-kind development where discerning buyers can find a home crafted with the highest quality of design and execution, and not one but every apartment features a spacious layout with double-height ceilings." The residences will range in size from 1,100 s/f one-bedrooms to 2,100 s/f three-bedrooms, with select homes featuring private outdoor space. On floors eight through eleven, the building will also offer four duplex penthouse apartments ranging from 2,300 s/f two-bedrooms to 3,000 s/f three-bedrooms Striving for LEED Silver certification, 456 West 19th St. offers residents an environmentally friendly lifestyle with low-VOC construction materials, filtered air and water in every apartment, individual climate controls, FSC-certified wide plank white oak flooring, and energy-efficient UV-blocking glass.
