Talking about experimenting with space! We love Shigeru Ban’s new ‘Cast Iron Penthouse’ – two new penthouses that will stand on top of the 132 years old residential and commercial building, Cast Iron House in Tribeca, New York City. The new penthouses are expected to hit the property market next month, with an estimated price of $12 million to $15 million.
Ban has been commissioned to design not only the rooftop additions but also the interiors. The modern addition will feature floor-to-ceiling windows that, thanks to its cantilever system, can be completely opened to connect the interior and exterior spaces. Inside, Ban plans to design the penthouses with a white metal theme and will feature white lacquer cabinetry, white lacquer desks and die-cast aluminum door levers. The building will also have a shared garden courtyard with 40-ft tall bamboo trees, a sauna and steam room, a game room and an exercise room.
A distinct feature of the penthouses is the Vierendeel truss (named for the Belgian civil engineer who devised it), a cantilever that allows for glass exterior doors to be completely opened, creating an uninterrupted expanse between the interiors and the surrounding terraces. Both units will have ample private outdoor terrace space, which will give incredible views of the skyline. While one penthouse addition will have four bedrooms at a size of 3,800 sq ft with 1,530 sq ft of private outdoor space, the other will be even bigger with five bedrooms and 4,560 sq ft of space and 1,430 sq ft of outdoor space.
Built in 1882, the stunning, original building has been fully renovated to preserve its architectural ornamentation, and will soon offer 11 other duplex apartments in addition to the two forthcoming penthouses. The concept behind the building is “a ship within a bottle,” said Dean Maltz, a managing principal at Shigeru Ban Architects and the executive architect on the project. The skin of the building is the bottle, while the interior, which will feature the 11 duplex apartments, is the ship. The duplexes will range from a 2,850-sq-ft three-bedroom to a 4,890-sq-ft five-bedroom and double-height living rooms of 17 to 25 feet.
New York is home to several luxury penthouses built over older structures, including Jennifer Aniston’s penthouse set on the 18-th floor of a pre-war building or the Skyloft Penthouses built above a 120-year old building. Of course the icing on the penthouse-cake would be Sheikh Hamad bin Jassim bin Jaber al-Thani, the Emir of Qatar who has been rumored to have spent $100 million to pick up the New York City’s most expensive penthouse that sits on top of the 90-storey, One57 building at 157 W. 57th St.
