Neil Denari’s HL23


Another addition to the burgeoning architectural wonderland that is West Chelsea.

This one is HL23, designed by Neil Denari, a new residential condo building for developer Alf Naman. It’s right next door to another far-out new condo, Lindy Roy’s High Line 519. Site work on the project began a few months ago, but construction is officially beginning this month.

The 14-story building bends and folds in response to the High Line, widening as it rises. Although now based in LA, Denari used to live in the neighborhood, and first became interested in the High Line after seeing Stephen Holl’s “Bridge of Houses” proposal back in the ’80s for houses on the High Line.

It’s also raising the bar for green buildings in the area, with LEED Gold certification and 100 percent green energy use planned.

The building will also be the subject of a special exhibition at the Museum of the City of New York. It’s called “New York Fast Forward: Neil Denari Builds on the High Line,” and it’s running from June 10 to September 14. More news on that later.


The building has also gotten a lot of press, both bloggy and papery.
