It is believed to be the most expensive condominium ever listed in the Northwest. Penthouse 4201 can be had for just under $14 Million.

Built in 2009, a complete renovation ramped up the place even higher in 2015. And that's sayin' something 42 floors up.

The 3,000 square foot deck wraps around the west, south and east side and includes an 8-person hot tub with a hidden tv.

The property is represented by Jason Mesnick, an NWG Broker. You may have seen Jason on "The Bachelor."
