Built in the early 1970's, the Broyer House sits on top of the Givat Ha'More Hill and overlooks the fields of Yizrael Valley. The architectural plan is based on local material and energy saving principles, innovative for their time. The house emerges from the ground with a lower mass built from natural, locally-sourced lava rocks. Its upper mass is made of smooth white plaster. Broyer House faces south and west, and uses natural sunlight that penetrates beneath the wide roof for warming the space in wintertime. The shape of the roof blocks the higher zenith sun from entering and heating up the space in the summer.
