Set on a constrained waterfront site near downtown Tiburon, Cliff House responds to a steep slope and compact building envelope by carefully stepping the residence between the street and waterfront below. From Paradise Drive, the home presents as a quiet, single-story volume, preserving a modest presence within the neighborhood before opening dramatically toward the water. Below, two levels of living space extend down the hillside to a sheltered grotto level at the shoreline, creating a direct connection to the Bay. Expansive glazing, terraces, and deep overhangs frame views toward Angel Island and downtown San Francisco, while a restrained palette of wood, stone, and dark metal gives the architecture a warm, grounded character connected to its cliffside setting. The result is a house that feels private and understated from the street, yet increasingly open and connected to the landscape as it descends toward the water.
