Philanthropists Bud and Betsy Knapp, then the owners of Architectural Digest, set out in the 1990s to create a personal living space that allowed for large-scale entertaining and civic events, could display an extensive art collection and met their need for privacy. Five years in the making, the gated estate bordering the Bel-Air Country Club is pavilion-style, with the indoors and the outdoors connected through the extensive use of glass walls and doors.
