Hl23, the first freestanding building in New York by Neil Denari

Famous architect Neil Denari designed HL23, the first self-supporting building and a unique project for New York City. The avant garde design shows reality building which was expected to be a landmark in the centre of the West Chelsia district. The building follows LEED Gold Certification environmental standards and became the subject of an entire museum exhibition.

The building is a 14 floor apartment tower building that competes to a unique and challenging site directly adjacent to the High Line at 23^rd street in West Chelsea arts district in New York. The structure is partly impacted by a spur from the elevated tracks that create the High Line superstructure. The site is 40' x 99' at the ground floor. The building was designed to expand possible built floor area of a restricted zone envelope.  The flexible geometry of the building stands very close to the elevated park of the High Line. The building fulfils demands with one unit per floor and three distinct yet coherent facades, a rarity in Manhattan’s block structure. The project’s geometry is driven by challenges to the zoning cover with a custom non-spandrel curtain wall on the south and north facades, and a 3D stainless steel panel facade on the east facing the High Line.
