Condo of the Week: $1.5 million for an extremely curvy penthouse near St. Lawrence Market

Bragging Rights: At 1,220 square feet, the terrace rivals the size of the interior. There’s a hookup for a gas barbecue and space for a good number of chairs—or, if the buyer’s aim is good, he or she might be able to set up a reasonable game of catch.

Big Selling Point: The unit boasts $100,000 in upgrades, including features like custom glass French doors leading outside from the living room. The doors are weighted so that they can be left open in the summer without the wind slamming them shut every few minutes.

Possible Deal Breaker: Anyone who prefers angular rooms may see the rounded, waving exterior wall as an impediment to placing furniture, rather than a unique design quirk.
