726 Lake St San Francisco, CA 94118

Spanning two levels this sophisticated residence designed by renowned Cass Calder Smith showcases natural light, an open floor plan and extraordinary park views. Sited on an extra-wide lot abutting Mountain Lake Park, the thoughtfully reimagined home celebrates its exceptional setting and light-infused interiors. Drawing daylight from numerous skylights and expansive windows, sunlight streams deep into the interior, creating a calm, even glow that shifts beautifully with the hours. The home's layout emphasizes flow both visual and physical. Open outlooks between rooms and outward to the park reinforce a sense of connection to nature while maintaining a distinctly modern sensibility. Refined materials, including rich American walnut floors throughout, natural limestone tiles in baths, and rift cut white oak cabinetry, underscore the architecture's warmth and restraint. The living area and kitchen form continuous space, oriented toward Mountain Lake Park and the Presidio. Here, the boundary between indoors and out dissolves. Large windows frame verdant park views and the east wall, clad with mirrored panels and vertical wood elements, reflects light and views back into the room. A wood-burning fireplace grounds the living area, while a Lindsey Adelman chandelier adds an ethereal counterpoint. The generously scaled, professionally appointed kitchen opens to a deck overlooking the park - ideal for morning coffee or evening relaxation. The formal dining room and the family room bask in bright, southern light. A dramatic, light-filled central staircase acts as both architectural focal point and spatial anchor. By day, a skylight animates the stair with natural light; by night, a striking David Weeks mobile light fixture transforms it into a sculptural moment. Upstairs, the primary bedroom and ensuite spa-like bath offer a serene, private retreat. While windows open to treetops and expansive views over the park, the suite's top floor location preserves privacy. A second bedroom with dramatic skylights and an ensuite bath functions seamlessly as a home office. A third bedroom with ensuite bath on the main level provides comfortable accommodations for family or guests. In every detail, this home demonstrates how modern design can be both expansive and intimate where light is not merely an amenity, but the unifying element that binds architecture, interior, and landscape into a singular, luminous experience.
