GIMME SHELTER

Makeup mogul Bobbi Brown has got her smoky eyes set on a new penthouse at 245 10th Ave., which she is now in contract to buy for around $5 million.

The two-bedroom, three-bathroom, 2,500-square-foot unit in the Della Valle Bernheimer-designed condo building is perched above the new second phase of the High Line park. An elevator opens directly into the apartment’s entry gallery, which leads to a 45-foot-long living room with a fireplace and a big eat-in kitchen. Stairs lead up to a roof terrace.

Listing broker Leonard Steinberg of Prudential Douglas Elliman is currently out of the country and could not be reached for comment.

Broadcast news

New York City radio icon Ken Dashow bought a second apartment at his East 25th Street building to expand the home he shares with his wife, Jane, from 1,200 to 1,850 square feet.

Dashow, a DJ at Q104.3, is using his $500,000 purchase for an expansion that will add a “work and play” element to their residence, his spokesperson says. The addition will include a studio with a voice booth that doubles as a guest room so that musician friends can work and crash there. The apartment will also include a tiki bar for parties including Super Bowl bashes.

There will now also be room to showcase the couple’s art, including a print by Paul McCartney that McCartney gave to Jane and a print of John Lennon’s lyrics, “Watching the Wheels,” given to Ken by Yoko Ono.
