The Seaport is known for seafood and expensive housing. If you have enough clams, you may be able to afford the neighborhood’s newest offering.

What does $50 million get you? Actually, it’s $49.5 million but what’s a half million one way or another?

How about a 10,000 square foot penthouse at the St. Regis Residences. Yes, that’s $5,000 per square foot, which would set a Boston record but is hardly close to New York or Beverly Hills prices.

You have two levels with floor to ceiling windows providing views of the Boston skyline, the harbor, and the less fortunate at ground level.

There is a double-height great room, a curved staircase and Italian marble flooring. Also included is a custom infinity-edge pool with a clear acrylic bottom, and a retractable Libart International glass roof. Not that it’s relevant, but the monthly condo fee is $21,870.83 and parking is only $1,060.
