Manhattan’s Upper West Side is one of New York City’s most luxurious neighborhoods, and it grants easy access to some of the city’s best cultural attractions and finest establishments. With the Lincoln Center, Central Park, Museum of Natural History, and Riverside Park to surround this pre-war architectural neighborhood, it’s no wonder why it’s one of the most desired.

The Cast Iron House, reimagined by Shigeru Ban, places two, white metal penthouses atop a cast iron building that’s exemplary of its Tribeca neighborhood.  Though the nuances between the two forms are distinct, the merging makes for a cohesive unit, with a proper synchronicity of rhythm in design.  Each of the penthouses makes use of a Vierendeel truss, which enables the glass walls on their bottom levels to free it to the open air, playing with the idea of living space, and smudging the demarcation between the interior with the terrace outside.
