In March 2008, in New York City, construction began on HL23, the first major freestanding building of acclaimed architect and vanguard theorist Neil Denari.

The sculptural fourteen-story residential tower will rise from a site on West 23rd Street half beneath the High Line elevated railway bed—slated for transformation into an urban park. The reverse-tapered eleven-unit structure will cantilever gracefully over the rail beds, creating a local landmark, cinematic views and unrivaled intimacy with the High Line for its residents.

Buying into this building means having an appreciation for architectural ingenuity; it’s likely that buyers would expect its Web site to be similarly inventive and playful. The interface caters beautifully to an obsessive, technophilic buyer through the transformation of a conventional site map into a spatial structure. Everything is immediately visible and accessible to visitors who will want to know and explore all facets of the building: renderings, fact sheets and a 3-D rotating model of the building.

• The site launched prior to the release of most of the marketing collateral (namely the 140-page brochure).

• HL23 is currently the subject of a full-floor exhibition at the Museum of the City of New York titled, “New York Fast Forward: Neil Denari Builds on the High Line.”
