Actress HEATHER LOCKLEAR and her husband, Motley Crue drummer TOMMY LEE, are paying in the mid-$2-million range for a home in Westlake Village with such amenities as a 21-foot-long, underground wine cellar and a master suite with a courtyard and a fountain.

Locklear co-stars in the new ABC sitcom "Going Places," and she appears in an upcoming CBS movie--"Dangerous Woman," starring Barbara Eden. Locklear was also a regular in the TV series "Dynasty" and "T.J. Hooker," and last year made her first feature film, "Return of the Swamp Thing."

The couple is buying a five-bedroom, six-bath, Mediterranean-style house that is being built on 3.8 acres.

"It's just about finished," said Mark Tyoran, who is the listing broker with Andrea Jacobs at Jon Douglas Co.'s Westlake office. David Blatt, a commercial real estate broker and a friend of the Lees, is representing them in the purchase, which is due to close escrow at the end of the year.

"They're developing an incredible view property, with a pool, in the gated community of North Ranch," Tyoran said. "It will have . . . a sauna and his-and-her baths in the master suite . . . a 40-foot long 'Great Room,' and a gym, all in about 7,300 square feet."

Locklear and Lee plan to decorate their new, single-story home in the same Victorian Country style as their two-story house in Woodland Hills, which is listed at $1,495,000 with Lee Hauser at Jon Douglas Co.'s Sherman Oaks office.

That house, a Tudor in a gated community, was newly built when the couple bought it four years ago, about the same time that they were married. It has five bedrooms and five baths in just under 5,000 square feet.

"He has a cabinet full of sound equipment that would rock the Coliseum," Hauser said. "There are speakers in the rocks by the pool and the waterfall . . . and there is a 23-foot-long recording studio in their attic."

Psychologist/KABC-TV personality IRENE KASSORLA and her husband, computer scientist NORMAN FRIEDMAN, are putting the finishing touches on their first home together, a $35-million project in Holmby Hills.

They've been building the home for more than four years on the three-acre site of the former JACK BENNY estate.

"He (Benny) didn't live here that long," Kassorla said of the comedian, who died there in 1974. "He lived on Roxbury (in Beverly Hills) for quite awhile, then sold that house and moved to a high-rise in Century City.

"But they (Benny and his wife, MARY LIVINGSTONE) were very unhappy in Century City, so they bought this property in '68 or '69 and did quite a bit of renovation (before Livingstone died there in 1983)."

Despite Benny's renovations, Kassorla and Friedman found that the house needed updating and was too small for them and so they razed it.

The end result even surprises Kassorla. "You start on paper, then add a little here and there and end up with a giant house."

The home is about 21,000 square feet in size with 7 bedrooms, 16 baths, 11 fireplaces and 5 kitchens, which makes her chuckle "because we're both watching our diets, and I get an anxiety attack whenever I get in a kitchen."

The home also has a grotto in the swimming pool and a 14-foot-tall, iron front door, which Kassorla designed. One of her daughters helped her with the interiors, the other helped with the landscaping. "We put in about three dozen trees," Kassorla said.

She is preparing a three-part report to appear on KABC's 5 p.m. news Oct. 31-Nov. 2, and she's working on her fourth book; her others include the bestseller "Nice Girls Do." Her husband is president of Daisy Systems Corp., which makes the daisy wheels for computer printers.

ELIZABETH TAYLOR'S Puerto Vallarta penthouse was being purchased by some investors from Northern California, but it fell out of escrow and is back on the market at $200,000.

The four-bedroom, four-bath penthouse, which the actress purchased in 1987, was first listed in February at $250,000. It's in a 156-unit building that has tennis courts, spas, maid service, a restaurant, golf course and marina views.

Elaine Dannenberg and Roger Wall of Fred Sands' Beverly Hills office share the listing.

LIBERACE'S Palm Springs house, where the pianist died in 1987, has been purchased after being in escrow for about eight months.

"The house wasn't in the greatest of shapes, and it just took that long to get it approved by the buyer," said George Thomas, who handled the transaction through the Rancho Santa Fe office of the Willis M. Allen Co. The buyer was described as a San Francisco man who paid $750,000.

He bought the house from the Liberace Foundation, which had put it on the market in 1988 at $850,000 after failing to get city approval to turn the property into a museum.

The seven-bedroom, 8 1/2-bath home, which was built in 1930, was a small hotel called the Cloisters before Liberace bought it in 1968.
