The acclaimed Neil Denari-designed HL23 condo development in Chelsea, which is seeking LEED Gold from USGBC, is set to welcome its first residents on June 1.

We closely followed construction at the Neil Denari-designed, LEED Gold-hopeful HL23 condominium project on West 23rd Street Chelsea here at gbNYC. Although occupancy was originally scheduled for the end of 2009, delays, including a June 2008 stop work order, pushed the schedule out, and the $22 million development is now all set to welcome its first residents on June 1 (just in time for the opening of the second section of the High Line, over which the brushed exterior steel and glass of HL23 cantilevers).

As you may recall, HL23 was the subject of an exhibition at the Museum of the City New York that highlighted Denari’s acclaimed design and the project’s green features, which include a curtain wall system projected to improve the 39,000-square-foot building’s energy efficiency by 15 to 25 percent over code, reflective roofing, a two-year green power purchasing agreement, construction waste management, and recycled-content building materials. HL23 continues to seek LEED Gold certification from USGBC.

Developed by Alf Naman, the 14-story HL23 includes nine full-floor residences and two duplexes, one of which is a penthouse with an 1100-square-foot wraparound private terrace. The reverse tapering of the building’s profile allowed Denari to create larger spaces on individual floors, which range to as much as 40 percent larger than the building’s footprint at street level.
Interior unit details include slab marble in the bathrooms, hardwood floors, and Nanz hardware. Interior designer Ryan Lawson is furnishing the interiors of each unit with vintage and mid-century furniture from Magen H Gallery and Sebastian + Barquet. The project team also included interior architects Thomas Juul-Hansen Architects, LEED consultants YRG Sustainability, and construction managers T.G. Nickel & Associates.
