New York, NY

Completion Date: Fall 2011

Owner: 23 High Line LLC

 

Program: A 14-story, 39,200-square-foot condominium tower that extends above the High Line, an elevated public park built on a derelict railroad track that runs along Manhattan's West Side. The building, which has a concrete substructure and a steel superstructure, spans only 40 by 99 feet at its base. Slated for completion in fall 2011, the project includes nine full-floor residences, a duplex penthouse, and a ground-floor maisonette with a private garden. 

Design concept and solution: Working on a narrow site, the architects wanted to find a way for HL23 to fit snugly and naturally into its surroundings yet also stand out as a landmark on the High Line. To capture the most floor area possible, they adjusted the silhouette of the building to contract and expand according to site constraints and zoning regulations. Where the High Line meets the HL23's south facade, they bent the curtain wall inward and pushed out the east facade to regain lost square footage. Opting for a what-you-see-is-what-you-get approach, the architects drew attention to the steel structure: white-painted steel pipes cross behind the curtain walls of the north and south facades, echoed by a white ceramic frit pattern on the surface of the glass. The east facade, which directly overlooks the High Line, takes a cue from the park itself. Like a kind of overgrown stainless steel stalk, this facade is composed of paneling embossed with a subtly wavy pattern inspired by the textures of the plant life below. To give residents privacy without interrupting the facades, the architects chose motorized shades, along with blackout shades for the master bedrooms. Designer Thomas Juul-Hansen reinforced their minimalist approach with painted gypsum-board walls, wood floors for the residences, and terrazzo for public areas.
