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.

The neo-gothic stylings of the iconic Woolworth Tower are providing for residential spaces in the top 30 floors with 40 units.  As of yet, no renderings of the interiors have been revealed - however, the penthouse in particular has been promoted as covering five levels in the spire’s patinated cupola, and will also have access to the original observation deck.  The storied tower of the Financial District, just over a century old, is currently, and will continue to function, as a commercial space.

50 West Street, the Helmut Jahn-designed, glass tower with rounded edges, is a planned 63-floor condominium for FiDi.  The column, jutting upwards from within Lower Manhattan, will offer residences with tall ceilings, and views of the waterfront and Battery Park.  The project was stalled a few times, but after extensive flooding in Battery Park and the surrounding area as a result of Hurricane Sandy, it was redesigned with some flood-resistant features.

443 Greenwich Street is undergoing a conversion to 53 condo units.  The Tribeca loft, and erstwhile book bindery, traces its history to the latter half of the 19th century, and will offer floorplans from 2,000 to 9,500 square feet, as well as a litany of amenities, including indoor pool, fitness center, sauna, wine cellar, private storage, and common rooftop terrace.

199 Mott Street takes a contemporary design, with a steady facade of brick, glass, and steel.  Its planned two- and three-bedroom units will have oak floors and bronze accents, making for an interior with a hardwearing, industrial robustness that matches the exterior.  It is expected to earn LEED-Gold certification, which makes sense given Alfa Development’s previous environmentally conscious project, Chelsea Green.
