Founded in 1895 by Danish immigrant Peter Janss, the family-run Janss Investment Company was responsible for developing an estimated 90,000 acres of Southern California property, including Holmby Hills, Westwood, and Van Nuys. But along with overseeing the development of Thousand Oaks and the Sun Valley ski resort in Idaho, Peter's grandson Edwin Janss Jr. was also a noted connoisseur of contemporary art. Per his 1989 obituary, Janss Jr. and his wife Ann "built a discriminating art collection over 35 years" that included works by Francis Bacon, Robert Rauschenberg, Richard Diebenkorn, David Hockney, and Andy Warhol, which the couple showcased in their gallery-like residence, now on the market.
Built in 1975, the property contains a 3,431-square-foot main residence with two bedrooms and two baths, plus a detached one-bedroom, one-bath bungalow. Features include "soaring ceilings," walls of glass, a "restaurant-style kitchen" with Gaggenau and Sub-Zero appliances, and a backyard with "two covered dining areas, a spacious sun deck, and a heated lap pool & spa." Sited on a 6,046-square-foot lot a few blocks north of Olympic in Sawtelle, the compound is listed at $2.995 million. (And, for startling comparison, here's grandfather Janss's stuffy house in Windsor Square, and father Janss's also-stuffy house also in Windsor Square.) Update 3/20: A tipster lets us know this appears to be an early work by Frank Gehry.
