The EXTREMES

Biggest Westside sale ever: The Knoll, in Beverly Hills, a two-story Georgian estate bought in 1984 by Marvin Davis for more than $20 million.

Biggest sale transacted in 1987: Liongate, purchased for more than $7 million by a land developer. Once owned by Kenny Rogers, the estate features a glass elevator that drops from the pool to a disco underneath.Most expensive garage: Steven Spielberg last year paid $1.3 million for the house next door to his 40,000-square-foot Santa Fe-style spread in the Pacific Palisades Riviera. The neighbor’s house is being torn down to make way for Spielberg’s garages.

Most expensive tear-down: A Japanese company last year bought two neighboring estates in Beverly Hills for $12 million and plans to tear down one of the houses to make way for a new mansion.

Most expensive condo on the market: The west penthouse of the Wilshire House. Recently reduced from $8 million to $6.9 million, it’s now a bargain.

Most expensive fixer-upper: The Pickfair estate, now in escrow. The estate, which Pia Zadora bought this year for about $7 million will get a $2-million facelift, real estate sources say.

Best sign of the times: A New York stockbroker last fall paid $6.5 million for an estate and its lot next door in celebrity-studded Broad Beach--but that was before October’s stock-market crash. Now the house is back on the market for the same price. “He just wants to get out of it,” says an agent.
