Developed by Alf Naman and currently in construction, HL23 is a 14 floor condominium tower that responds to a unique and challenging site directly adjacent to the High Line at 23rd street in New York’s West Chelsea Arts district.  With the first phase opened from July 2009 (12^th-20^th street), the High Line will extend north until its terminus at 34^th Street in its second phase to open in 2010.  This new linear park, elevated above the street 25ft on existing rail infrastructure, offers people new chances to interact with the city’s rich architectural heritage and its vibrant future.  Designed by Field Operations and Diller Scofidio + Renfro, the High Line Park advances a merger between various urban ecologies both found and implanted. HL23 is a structure precisely shaped by a confluence of these forces.
