‘Traditional’ dollhouses can be dated back to 16th century Europe, and contrary to popular belief, were actually not meant to be played with, but were rather meant as miniature display cases for adults’ viewing pleasure. Today, dollhouses are largely gendernormative toys for young girls to exercise play-fantasies of domesticity. Yet, despite the troubling reinforcement of gender roles to which toy dollhouses contribute, they operate within a unique context of multiplicity, customization, and unique program distribution in section—this last feature evocative of Adolf Loos’ raumplan. Therefore, taking the dollhouse as a departure point, this project generates the “fosterhaus,” a 1:1 scale ‘dollhouse’ that is programmed as a collection of complementary experiences aimed at fostering a sense of home in orphaned children. Deploying social-psychology research on child development, and understanding the problematiques often associated with raising children in a foster home, the Fosterhaus is choreographed as a collective lived-in educational experience that allows the children-residents to customize their spaces and, through play, create their own feeling of belonging and family.
