HGHB replaced the 50-year-old clubhouse at Alpine Hills Tennis and Swimming Club with a new facility that capitalizes on the expansive views of the valley and tennis complex as well as the pool complex and oak woodlands. Using pavilion roofs extended well beyond the exterior glass walls, the viewing decks and glazing receive shade from noon on year-round. The interiors are characterized by expansive light-filled spaces with exposed structure and accents of wood and stone.
