High Line 23 Brings New Green Tower to Chelsea Skyline
High Line 23, or HL23, is a new green building from Neil M. Denari Architects that is currently under construction and turning heads soon in the Chelsea art gallery district on Manhattan’s west side. The structure is a 14 floor mixed use of gallery space and condominiums with amazing views of the evolving High Line elevated park preservation and green space reuse project. With an impressively small footprint of just 40’ x 99’ and a multitude of green building technologies, HL23′s cantilevered silhouette is made even more exquisite by the expected achievement of LEED Gold certification.
The building’s geometry is an ambitious response to the development site’s limited space, maximizing zoning restrictions and expanding the possibilities out over the park. Naturally ventilated and daylit spaces fill 11 residential condominiums fitted with water conserving fixtures, energy efficient appliances and low VOC materials. Reused and recycled materials are incorporated throughout the structure and 75% of construction waste will be reused and recycled to be diverted from landfills.
A high-performance building envelope and highly reflective roofing material will decrease HL23’s heat and energy loads, as well as help moderate urban heat island effect. From its tiny footprint, HL23 towers skyward housing 39,000 square feet with homes between 1,850 and 3,600 s.f., including a top floor penthouse that will run $10.5 million.
While among the leading architects of his time, Denari will count High Line 23 as his first free-standing building when completed in late 2009 – an enduring green design trend that we certainly hope continues.
