515 West 23rd Street | Chelsea

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 offers the luxuries and comforts expected from a luxury NYC condo, from hotel-style amenities to spacious, light-filled apartments for sale.

What's most impressive about the green building elements on display at HL23 is how seamlessly its star architect, Neil Denari, has integrated sustainable design elements and contemporary Manhattan condo luxuries. HL23's energy-efficient design incorporates reflective roofing, energy-saving lighting and ventilation, water saving appliances and the use of recycled materials and low-VOC finishes in each condo for sale. But all that sustainability doesn't at all compromise the luxurious living experience at HL23. Those huge windows in each condo for sale at HL23 are impressively energy-efficient, but they also admit dazzling views of the High Line and bathe each apartment in natural light. In each apartment for sale at HL23, form follows function to striking effect. Architectural grace notes such as soaring ceilings and private outdoor terraces share space with such luxurious design elements as luminous oak floors, spacious modern baths and marble-accented gourmet kitchens.

The hotel-style amenities at HL23 are as impressive as those on offer at any luxury condominium in Chelsea. A 24-hour doorman and 24-hour concierge add convenience to the living experience at HL23, as does the copious storage available for condo owners. HL23 also boasts a state-of-the-art fitness center, but the greatest amenity of all is HL23's prime Chelsea location atop the High Line itself. One of the most uniquely well-designed condominium listings in Manhattan and certainly one of the finest new condos in Chelsea, HL23 is both an impressive architectural achievement and a terrific place to live.
