The Henry J. and Alyce Kaiser Estate is a one-story, International Style residence following Mies van der Rohe’s architectural vocabulary having an off-centered cross-shaped plan, a flat roof design, with large glass sliding doors along the ocean front elevation. The foundation is concrete and the walls are concrete with a stucco finish or silver travertine stone veneer. The roof is flat with a thickened edge made of steel web trusses. A large covered porte cochere protrudes from the entry hallway, serving as one of the legs of the cross-shaped plan. The interior of the house reflects the International Style in the white ceilings, white floor, and white and silver travertine-clad walls. The house is located at Portlock, an early upper-class neighborhood, popular from the 1950s onward. The house fronts the ocean, and high stone/concrete walls along Portlock Road shelter the property. Built in 1959, the Henry and Alyce Kaiser Estate is locally significant under Criterion B for its close and unique association with Henry J. Kaiser, one of the America’s top business leaders and industrialists of all time.
