The Accessory Dwelling Unit (ADU) developed by First Office for the City of LA is built using prefabricated Structural Insulated Panels (SIPs). The panels’ laminated structure, a sandwich of foam insulation and Oriented Strand Board, allows for expedited construction schedules and offers high environmental ratings, producing great value for the owners.
The office has recently completed a prototype of this ADU, showcasing the construction method at the SCI-Arc Gallery in LA’s Arts District. Tucking the infrastructural and mechanical programs (such as closets, built-in shelves, kitchen counters, and bathrooms) into the vertical SIP supports, the house follows an efficient and open plan. While the design of the ADU is minimalist in its form and expression, it maximizes the materials’ environmental performance, taking into account sustainability factors and flexibility of construction, as well as SoCal’s indoor/outdoor lifestyle. The house has a seamless relationship with its backyard and the main house through large windows and sliding doors and offers an opportunity for a roof deck above.
