CONTRACT SIGNED
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. Glass facade panels will be over eleven feet high and six feet wide each, creating soaring floor to ceiling visual spans of up to 45 feet wide in each of the building’s unique homes. Lucky residents will enjoy unrivaled intimacy with the plantings and paths of the lyrical new High Line Park, as well as breathtaking panoramas north and south from each unit.

The building’s east faade will have the appearance of a monumental public sculpture clad with a system of custom-designed, three-dimensionally curving stainless steel panels, each 11.6 feet wide.

The column-free interiors of HL23 have been designed by noted architect Thomas Juul-Hansen.

Similar views north from the master bedrooms bring the city inside. Sensual and calm, every home features a gracious entry foyer off the private keyed elevator. Floors throughout the building are rift cut solid oak planks with two layers of sub-floor for high levels of sound insulation. Master bathrooms have marble slab walls and stone slab floors; custom-designed, glass-enclosed “wet rooms;” up to 11 foot-long vanities; a
