Along with a big new promotion to president of the restructured and renamed Viacom Music and Entertainment Group, veteran showbiz executive Doug Herzog upgraded his residential circumstances — so we first heard from Big Apple property snitch Polly Wannacracker — with the $5 million purchase of a swanky new condo in a brand spanking new boutique building in New York City’s white hot and blisteringly pricey West Chelsea neighborhood.

The two bedroom and 2.5 bathroom corner unit, just shy of 1,700 square feet, per listing details, and last listed at $4.9 million, features a brief but proper entrance hall and a combination living-dining room with hardwood floors, multi-paned floor-to-ceiling windows and a slender, glass-railed balcony that overlooks the acclaimed High Line park. The compact, well-equipped open-concept kitchen is expensively dressed with cerused and quarter-sawn white oak cabinetry, slab marble countertops, a full complement of high-quality appliances and a convenient laundry closet. The bedrooms flank the main living space for optimal privacy, and the slightly larger master has two walk-in closets and a roomy if windowless bathroom with dapper bronze fixtures, radiant-heated brown marble floors, and walls sheathed in white statuary marble. The newly built building provides its well-heeled residents ’round-the-clock doorman and concierge services, a club room for large parties, a state-of-the-art fitness center and on-site parking.

On the West Coast, Herzog, who oversees a healthy handful of cable TV channels including Comedy Central, MTV, VH1 and Logo, also maintains a 1930s Georgian Colonial in Los Angeles’ low-key-but high-cost Brentwood Park ’hood that property records indicate was scooped up in June 1999 for $3.15 million. Fun Fact: Herzog’s L.A. home was briefly owned in the mid-’90s by uni-named comedienne Roseanne, initially with her second husband, Tom Arnold, and then with her former bodyguard and third husband Ben Thomas.
