For the measly sum of $11.215 million, you could become the proud new owner of this full-floor penthouse space at the Ritz-Carlton Residences on the Magnificent Mile. The 6,597 square foot unit occupies the entire 39th floor of the building, and similar to other high-end highrise residences, is being offered as a raw space. The unit is surrounded by outdoor terraces, offering nearly 900 square feet of outside terrace space which offer sweet downtown views. The unit is being listed by Coldwell Banker's luxury division. The listing marks the second week in a row that a $10+ million raw penthouse space has hit the market in Chicago, and has continued the shake up in the city's top 25 priciest listings. With the city experiencing a major real estate comeback this year, perhaps we could see even more ultra-luxury residences come out of the woodwork.
