The Wraparound House by SAW is a beautiful example of a 1930s Spanish Revival home, situated in San Francisco.
The subtlety and curves of the home's design are what make it so special.
The Wraparound House by SAW - Spiegel Aihara Workshop is an architectural renovation of a 1930s Spanish Revival home in San Francisco. The project adds 4,738 square feet of interior space for the family, including the garage. The new landscape provides ample outdoor space for the family to enjoy.


The project not only offered the chance to recover the best features of a historic home but also to remediate and stabilize a landfill subsurface beneath the home. Excavation of the top 4-6 feet of soil was necessary for remediation of the ground condition. Excavating the top layer of soil allowed the entire house to be lifted and the foundation was replaced with a thicker mat slab. Redistributing load and shear-bearing walls throughout the ground floor opened up possibilities for a different spatial configuration with three interlocking bedrooms across a 25-foot width.

The ground plane is lifted up through a series of terraces on four levels to create a continuous experience of the landscape. This was made possible by the soil remediation process. SAW partner and landscape architect Megumi Aihara started from scratch with the landscape, bringing in new soil to support new planting. Artificial turf was used for lawns where the earth was not already in place. Artificial turf also contributes to site drainage and reduces overall water use.

The new planting provides a structured but loose backdrop to the house, emphasizing contrasting textures with round sheared boxwoods set within soft billowy grasses.

Interior stairs serve as the core of a house, while exterior stairs provide access to different levels via an outdoor terrace. Each level has another relationship to the outdoors, with the roof terrace providing stunning views of the Golden Gate Bridge and the Bay.


The roundness theme was inspired by the many arched doorways in the existing house. Curved arches were cut up and flattened so that interior corners would be smooth, rounded surfaces encircling the central, sculptural stair of the house. The name "Wraparound" comes from the slight variation in corner geometry. Curving surfaces bend light gently, making it difficult to see where one space ends and another begins and defining movement throughout the house.
