Join Open House host Sara Gore for a tour of stunning homes in New York and California — from a pair of penthouses in Tribeca that embody contemporary design and architectural excellence to a jaw-dropping 32,000 sq. ft. estate known as Knoll House in Pasadena with its very own art museum to to a redesign of a 1940s house (lovingly nicknamed "the jewelry box) in the Mount Washington section of Los Angeles that is a labor of love, as well as an ode to a love of travel and fashion — that are as striking and airy as they are inviting and unique.
