The App House was designed under challenging conditions caused by local hillside ordinances, building codes, and imposed restrictions on hillside construction. The house's site is located on an uneven, downhill slope lot in Hollywood Hills, California, while offering panoramic views of Los Angeles City. The goal was to create a design that would comply with the building codes and, at the same time, strategically implement these stringent criteria into a sculptural and efficient design solution that seamlessly engages with the surrounding site.
