$18 Million Tribeca Penthouse Customized by Dead Billionaire

Last week's priciest pad to hit the market is the jewel of 200 Chambers Street's eye: the 4,700-sq-ft penthouse built by an Italian billionaire who died before moving in. The ask is $17.995 million for 4 bedrooms and 4.5 baths and the detailing ismeticulous (none of this wood-paneled identity crisis business). The deets: three exposures, including a view of the Hudson from 30 stories up and a 53-foot wall of floor-to-ceiling windows; a floating limestone tub; Poliform stainless steel kitchen; and an in-house water purification system.

The acoustic amenities, we imagine, are Patrick Bateman-approved: 

"The speakers are hidden under plaster in the ceiling. The lighting is museum quality. The powerful, in-home HVAC system is tucked away behind two thick doors. Each wall and all ceilings and floors are acoustically engineered to never let sound pass through."

Don't get too attached to the furnishings: the brokers at Platimun Properties hired a team to trick out the interiors with artwork (Andy Warhol, George Condo, Marilyn Minter) and spendy furniture like that $63,000 accordion sofa
