A 4,550-square-foot triplex on Central Park West has hit the market with an asking price of $24.5 million and an impressive alternate use which might dazzle the musically inclined.
The co-op’s sprawling living room doubles as a chamber-music recital hall, according to a 2015 Architectural Digest spread dedicated to the unit.

"It was something [the owner] always wanted," said Stephen Lee of SLR Design and the owner’s brother.
The room has been the setting for many musical performances, events and fundraisers, as the owner is on the board of some music-related charities. "Sometimes it's a string quartet or cello chorus playing, sometimes it's a loud band with amplifiers," Mr. Lee said. "There's a four-inch high empty space with concrete slabs above and below, just below the 30th floor of the building, so no sound or vibration penetrates down to the lower floors."
Mr. Lee worked with acoustical engineers to "tune" the room so that it would be appropriate for concerts and recitals.
"The ceiling planes break up the sound, and all the fabric walls in the room are backed with an acoustically absorptive material," Mr. Lee said. "We also worked with the acoustical engineers on the rest of the apartment including the kitchen atrium, which even though the ceiling is 30-feet high, feels acoustically like a nine-foot ceiling space."
The complete redesign took around three years total, according to Mr. Lee, including approvals, construction and design.
Property records show the unit was bought in 2008 for $8.94 million.

"The entire layout changed to the point where part of the master bedroom became a foyer. Everything moved around," Mr. Lee said. Meanwhile, the space that now serves as the living room recital hall, had formerly been another section of the master bedroom along with a master bathroom, closet and storage space.
Beyond the mini music venue, the four-bedroom apartment has a glass, limestone and blackened steel cantilevered staircase, a chef’s kitchen with a wood-slatted atrium, Central Park views and a third floor dedicated to a golf simulator room, according to the listing with Deborah Grubman, David M. Adler and Paul Albano of Corcoran, which went up on Monday. The brokers did not respond to requests for comment in time for publication.
The siblings have worked on four projects together. "She’s sort of the ideal client. She doesn't care about the overall design and details as much as I do," said Mr. Lee. "She cares about the floorplan and layout. Everything else she lets me have free reign."
His sister, Mr. Lee added, was selling now that two of her children live away from home.
