The New York Superrich and Their Super-Luxury Housing Amenities

Over-the-Top Amenities: Sweating the Details.  (The New York Times, 1/28/2015)

Home, it would appear, is where the hamam is. 

At least for the superrich. For along with the Olympic-size pools, children’s playrooms designed by experts in early-childhood development, basketball courts, demonstration and catering kitchens, lounges or “great rooms” with fireplaces, curated libraries, guest rooms, full-size gyms, spinning rooms and yoga studios, the hamam (pronounced hah-MOM) has joined the amenity package, as the brokers say, of the luxury development market. Or “super luxury” market, which is to say buildings where the price per square foot begins at about $3,000.
