Project #1! Plan North’s very first project set the stage for the work we’ve done ever since: maintaining client vision through the development of innovative engineering solutions under complex constraints.
Located just south of San Francisco, this hillside residence required an engineering response shaped by the site itself. Poor soils, steep grades, and some of the highest seismic demands in the country led to our design of a unique rigid grid foundation system bearing into weathered bedrock. The result was a stable base for both the modular and site-built portions of the home.
The sloped site became part of the architectural solution: a daylit basement anchors the residence into the hillside, while the upper floor opens to natural light and views through the trees.
In many ways, this project still reflects what drives Plan North today: solving complex problems through intentional coordination, technical rigor, and engineering solutions developed in service of the client’s vision.
