About

Featuring cinematic views, eleven extraordinary full-floor and duplex residences, and a daring sculptural design that has already won accolades, HL23 will be the first freestanding building by internationally celebrated theorist and maverick architect Neil Denari. The spandrel-free north and south curtain walls of HL23 – a reverse taping tower that will cantilever over the High Line elevated railbed — consist of some of the largest single-pane windows ever used in residential high-rise construction.
