The High Line Building

The High Line Building at 450 West 14th Street in Chelsea is perhaps Manhattan's most daring new green office building.

Developed by Charles Blaichman and designed by Morris Adjmi Architects, 450 West 14th Street is perhaps Manhattan’s most daring green office building. The tower – dubbed The High Line Building – sits above an existing three-story masonry industrial building along 9th Avenue, straddles the High Line, and is seeking certification under USGBC’s LEED for Core and Shell rating system.

Blaichman and Morris Adjmi themselves are no strangers to unique, high-profile New York City projects; Blaichman’s efforts include his Richard Meier-designed condos on the far west edge of Greenwich Village, while Morris Adjmi saw its new arena for the New Jersey Devils- the Prudential Center- open up to much critical acclaim recently out in Newark.

The High Line Building is best-described as a boutique green office building that will also offer 8,000 square feet of retail across two different ground-floor spaces. In addition to its LEED-CS application, the 11-story, 100,000 square-foot tower offers unique office and retail frontage and access to the High Line. Green features include efficient lighting, plumbing, and insulation, and low-VOC and FSC-certified finishes.

Certainly the project’s most unique design element though is that the High Line park itself will actually run for 103 feet through the lower floors of the building, which are actually a converted former beef processing facility; the upper six floors are new steel construction.
