It’s been few months since Morris Adjmi presented plans for his twisted tower at 837 Washington to the Landmarks Preservation Commission. He returned on Tuesday with a scaled-down version of the original design. The architect brought two 3-D models to better illustrate the before and after versions. The body of the exoskeletal steel structure still pivots clockwise atop a 1938 art moderne market building, but now it does so at a reduced height of 84 feet, instead of 113. Still, lopping off two of the seven stories from the original design may not be enough to satisfy commissioners who seem to be scratching their heads over how to address the major mood changes in Gansevoort Market Historic District, which sits within the ever expanding design glow of the High Line.
