The Mountain House had a heavily fenestrated north elevation to take advantage of the mountain views. That, coupled with the open screened porch, provided a challenging design to brace the structure against lateral wind loads. Two-story shear walls with openings detailed provided lateral bracing on the north elevation along with shear walls in other solid wall sections. The screened-in porch used shear walls anchored to posts and beams below to transfer loads to foundation walls and piers. Retaining wall foundations were utilized to accommodate the steep mountainside conditions.
