There are NYC condos near parks, and then there's HL23, a luxury condominium at 515 West 23rd Street that's actually cantilevered over the High Line park in Chelsea. The High Line has been acclaimed by Manhattanites and architecture critics alike for its combination of forward-thinking sustainable design and slick NYC style, and the same can be said of HL23. Designed to meet LEED Gold standards, HL23 is one of the greenest condos in Chelsea, and certainly one of the most striking-looking new condominiums in the West Chelsea Arts District. HL23 boasts a multitude of green design features, but it also delivers the luxuries and comforts expected from a luxury NYC condo, from hotel-style amenities to spacious, light-filled apartments for sale.
