This Upper East Side luxury condo tower comes with a music studio designed by Lenny Kravitz

A new luxury condominium development on Manhattan's Upper East Side has launched sales today, and it has some unusual features.

The Kent is an 83-unit tower built in an old-fashioned Art Deco style - but it's decked out with every amenity a contemporary buyer would want. That includes a one-of-a-kind "Sound Lounge" designed by Kravitz Design, helmed by famous musician Lenny Kravitz.

"The Sound Lounge was inspired by one of my personal recording studios," Kravitz said in a statement. "We wanted to create an inviting and inspiring multipurpose environment where the residents can play music together or practice their instruments."

It will be stocked with a full set of instruments, amps, and practice equipment for both professional and amateur musicians to play. And that's not the only specially designed room: there's a drawing room with a fireplace, a garden salon with a billiards table, and an "interactive play space" called Camp Kent.

Developed by Extell Development Group, The Kent was designed by Beyer Blinder Belle with interiors by Champalimaud and landscape architecture by West8. Units will start at $2.45 million a pop. Penthouse pricing has not yet been released, but it could be as much as $20 million.
