Closing act for WeHo dynasty

Actress and author Joan

Collins, who gained fame as Alexis Carrington on the prime-time soap opera “Dynasty,” has put her condominium at the Sierra Towers in West Hollywood on the market for $4.495 million.

The two-bedroom, three-bathroom unit has about 2,300 square feet of living space. Located on the quiet northwest corner of the 25th floor, the residence takes in sweeping views of the hillside. A sliver of Beverly Hills and the ocean are enjoyed from the large outdoor terrace.

Walls of glass in the main living area and a master suite with a soaking tub are among features of note. Vibrant marble floors and mirror-backed built-ins keep up the glamorous vibe.

The floor plan, one of the largest in the celebrity-magnet building, was originally three bedrooms and could potentially be converted back, according to listing agent Joshua Greer of Hilton & Hyland.

“More and more, we are seeing buyers bring in their own architect and their own designer to create their own living space,” Greer said. “There’s a lot more flexibility [to do that] at the Sierra Towers.”

Collins, 84, has scores of television and film credits, including the musical comedy “The Opposite Sex” (1956) and “Dynasty,” for which she won a Golden Globe. More recently she appeared in the series “Happily Divorced” and “The Royals.”

She bought the residence a decade ago for $2.7 million, property records show.
