The Christiansen House ~ Designed by world-renowned engineer Jack Christiansen and legendary architect Paul H. Kirk—two Modernist icons behind many of Seattle’s most iconic structures—this was Christiansen’s own residence, a personal expression of his structural vision & life’s work. A bold interplay of engineering & art, the home’s dramatic hyperbolic-paraboloid thin-shell concrete design—pioneered by Christiansen—appears to float above the living space, giving way to floor-to-ceiling glass and sweeping west-facing views of the Sound & the Olympics. Sited on 2 acres with resort-like grounds and 175' of waterfront with beach stairs leading to a large deck atop the bulkhead. An irreplaceable work of NW Modernism, born of legacy & innovation!
