A Steep, Sloping Lot Becomes a Hillside Family Oasis in San Francisco
In a quiet residential enclave, steps away from the small but spectacularly scenic Tank Hill Park, an existing midcentury home on a challenging site has been completely reimagined to take advantage of both panoramic city views and a private wooded landscape. The home’s residents, a young well-traveled family, wanted to create a place of refuge where they could be both engaged and removed from their beautiful surroundings.
From the start, the steep, sloped lot proved to be both a challenge and opportunity. "On a hillside site, we often try to use the differing topography to provide a variety of spatial experiences that reveal themselves as one moves through the home," explains John Maniscalco, founding principal of John Maniscalco Architecture.
Above the kitchen and dining room, a glass bridge connects bedrooms on the third floor. "The glass flooring allows the southern light to penetrate farther into the space, but also creates a special moment of pause to experience the scale and volume of the space below and towering trees beyond," says Maniscalco.
For Maniscalco, the first order of business was carving back the hillside to create new space and volume that would bring light deep into the home. "Given the space and orientation, the previous home was dark and starved of natural light," Maniscalco explains.
Digging out a chunk of the hillside in the rear allowed the jmA team to introduce a rear yard that didn’t exist before, as well as create a void in space that would let light in. Beyond carving away the hillside, the jmA team was also able to capture additional space beneath the existing home.
The home's main entry—two levels off the street—forces guests to get intimately acquainted with the steep topography of the site. Although the home's residents have the option to enter via garage and interior stair, guests instead travel up exterior stairs at the corner of the site, passing the planted neighboring lot to reach the home's front door.
"We used the steepness of the site to do something a bit unusual: we carved out an additional floor of occupied space below the living levels, but still within the envelope of the previous home," says Maniscalco. "In San Francisco, finding new space in that manner is a bit of a magic trick."
Intimately tied to the steep topography, views and experiences change as one travels through the home. Traveling up the steep entry to the living level on the second floor, the entry space offers access to both the living room to the north, and private dining and kitchen area to the south. Wide-plank European white oak flooring, and Pietra Serena limestone slab inlays bring an organic warmth to the space.
The dramatic gathering space enjoys seamless connection to the hillside backyard on one end, and unobstructed city views on the opposite end. Traveling vertically through the home, "the experience shifts to expansive city views and views to the Marin Headlands and beyond, creating a sense of your place in the larger environment," reflects Maniscalco.
"From most areas of the living level, you can simultaneously see and experience both the towering trees to the south and sweeping city and bay view to the north," says Maniscalco. "The careful placement of this floor level and creation of this spacial experience was a real cornerstone of the project."
Anchored in nature, the residence is entirely site and client specific. "The house would not make sense anywhere else, even in other locations on its block," says Maniscalco. "It’s a connection to the site and to the city that gives the house a sense of grounding and serenity."
