It’s Free to Look: 106 East 71st Street

What do you get when you combine two massive Upper East Side apartments into one? A really great game of Clue for one.

Thanks to its recent transformation from two apartments into a single-family home, this 25-foot-wide, six-story townhouse at 106 East 71^st Street has two entrances, two maid's rooms, two powder rooms and even two wet bars, according to the Corcoran listing. And with six bedrooms, seven bathrooms, a playroom, a gym, an oak-paneled library, a den, a study and at least a few more rooms we missed, there will always be somewhere new to hide the revolver.

The former home of an Orange County heiress, the renovation retains the feel of an Old World manor ripe for intrigue. But you can buy a lot of board games for the $28.8 million cost of 10,000 square feet of prime real estate a block from Central Park. — Laura Kusisto
