Swatt + Partners Shape a Hillside Home Overlooking San Francisco Bay

Rising along a ridgeline above San Francisco Bay, the Lagoon View Residence occupies a steep site in Tiburon, California, reached by a sequence of snaking roads that open onto sweeping views of the city skyline, the Golden Gate Bridge, and the Pacific beyond. The residence was realized through a recent remodel and addition to an existing home, with Swatt + Partners shaping the work as a contemporary intervention that takes direction from its setting.

Three-story modern house with large glass balconies, elevated on stilts, surrounded by grasses and trees on a sloped landscape under a clear blue sky.

Originally a 4,753-square-foot house that had undergone a series of renovations, the existing structure was visually and spatially fragmented. In response, Swatt + Partners unified the house into a more cohesive composition with a plan that remains consistent from one level to the next. Open sightlines and an expanded relationship to the exterior were central to this reorganization, allowing views to register fully throughout the interior. The plan prioritizes clarity of movement and orientation, while materials and structure work together to anchor the home to its hillside location.

Shifts between openness and enclosure shape the experience of Lagoon View. On the north, entry-facing side, solid stone volumes and vertical structural elements establish a sense of weight and enclosure. To the south and west, floor-to-ceiling glass walls, a cantilevered roof, and terrace extensions open the interior to bay views. These horizontal projections extend living spaces outward to create a continuous relationship between interior rooms and exterior decks while providing shade and framing sightlines.

Interior spaces by local firm Leverone Design showcase a balance between custom work and select made-to-order pieces, including works from the likes of Coup d’État, Jun Aizaki, Holly Hunt, and more. Outdoor furnishings from Zachary A. Design, RH, and Niche are arranged along the deck in response to the expansive bay-facing vistas, while a restrained approach throughout the interiors sets the stage for the clients’ capacious art collection, which includes works by Pablo Picasso, Ansel Adams, Salvador Dalí, Alberto Giacometti, Lin Fengmian, Wu Guanzhong, and Henry Moore.

Landscape design by Berkeley, California–based Thuilot Associates responds directly to the property’s natural topography, with paths stepping down the hillside through planted terraces and outdoor rooms, tracing the slope from street level to the lower edge of the property. Material continuity also carries through the exterior envelope, where integrally colored cement plaster, stained tongue-and-groove cedar siding, Windsor limestone, and clear anodized aluminum windows form a cohesive palette, executed by Stroub Construction. Together, these elements reinforce the home’s spatial clarity and its relationship to the surrounding terrain.

  • Blackened Wood Apartment

    Taiwanese architecture studio CTT Architects designed this interior project for a doctor in Taipei City. The apartment is located on the 21st floor of the residential tower nestled in the mountains surrounding the Taipei Basin. The design concept places emphasis on the connection to the surrounding vistas. In contrast with the original layout, the living area has been rearranged such that one can enjoy the amazing urban night views whilst introducing the external greenery inside during the day. We have also tailored the layout to meet the requirements of the client’s modern life. Following a busy day at work, he can completely unwind in the living room in the midst of the mesmerising urban night views; and be awoken by the dappled morning sunlight reflecting off the surrounding green mountains. We believed that every aspect of an interior design requires a bespoke response to its own contextual surrounding as well as to the individual needs of the occupants. The different spatial functions such as bedroom and bathroom are seen as different grey units in the public space. However, homely styling is found inside the master bedroom. Wooden finishings are used to complement subtle light grey walls allowing the stunning views to be the main element – lush green mountain landscapes. At the entrance to the apartment, the simple grey wall with a small bench gives an air of simplicity in complete contrast with the mountain views seen through the expanse of the three window units, which speak for themselves. In the kitchen and dining area, the open plan provides ample space that can be adapted flexibly to suit the changing needs of the modern city dweller. In terms of material selection, fine textured black charred timber panels are deliberately chosen to frame the surrounding mountain and city views. The design strategy is to use the black charred wall to contrast with the green and sky during the day; at night, the blackened panels blend seamlessly into the night view. The custom-made black island comes with black taps to contrast with the white kitchen joinery behind. When it comes to detailing, our approach is to delineate different architectural elements through shadow gaps. For example the walls and ceilings are detached using shadows gaps which are also accentuated by indirect lighting after sunset. Every architectural element has been detached including the ceiling, beams, and walls to showcase themselves as individual elements and avoiding detractive decorations.
