CAL 320 Technical Description

CAL 320 is a studio type ADU having a dimension of 20’ x 16’ with a gross area of 320 sq.ft. It has a shed-type roof. The design for CAL 320 aims to maximize natural lighting inside by having wide glass windows with overhang in the kitchen and bedroom. If privacy is opted by adding blinds or curtains in these areas, the clerestory windows that sit ten feet from the floor allows for natural light to flow in. The interior is composed of a bedroom, 1 toilet with shower space, an L-shaped kitchen, a counter dining space for two and a wash/dry area. The bedroom area has built-in cabinets and can comfortably situate a queen-sized (60” x 80”) bed with space to spare for a side table. The toilet can fit a lavatory, water closet and a 2’8” x 5’8” shower area. Standard package features and finishes for CAL 320 are shown in the table below. Upgrade options are available depending on client preference.

A Sustainable,
Eco-Friendly Home

During the construction process, our prefab homes generate about 80% less waste then standard site built homes.  A controlled factory setting allows us to use construction materials in a more efficient manner.  In addition, waste and poor workmanship caused by weather is eliminated.  The National Association of Homebuilders (NAHB) states,  “There are tremendous benefits to building parts of the home in a controlled facility, materials are protected from the weather and used in a more efficient manner.”
