The California Roll project is a customizable and mass-produceable system. Structural Insulated Panel (SIP) building systems are assembled with minimal framing and minimal waste due to their pre-manufactured nature. SIPs can be cut, mitered, punched, or milled then assembled conventionally. 

The single family house follows a “shotgun” type with regards to circulation. The program, however, is double stacked; a super dense crystalline nucleus of private space. The project presents dual formal languages and organizations: A conventionally assembled, open plan SIP shed surrounds a complex, custom and formally independent private envelope. The private space and private form is treated as furniture - the parts are of a smaller scale and they are highly adjustable. The duality pushes the construction conventions of SIPs.

 The complex private form gives passive cooling and ventilation through high operable windows and chimney openings. Roofing grooves capture and funnel rain water to a cistern. Photovoltaic panels and porous paving are applied to the conventional SIP shed portion of the house. Cool air draws in from low hopper windows along the circulation corridor.
