The six-story townhouse at 22 East 81st Street was built in 1883. Starchitect Robert A.M. Stern tried his hand at a redesign in the 1970s?and the house has been stuck in the 1970s ever since. Except when it comes to pricing, that is: the building is now on the market for $15.95 million. And it isn't a single-family home yet. There's a "dramatic" 2BR owner's triplex (which we assume is the unit pictured), five free-market 1BRs, and a rent-stabilized studio. The free market leases go until end of October, and the rent-stabilized lease ends in mid-2014, giving a buyer plenty of time to bring his or her architect to the place. Perhaps Stern would be willing to come back.
