To Build Law, the forthcoming documentary directed by Joshua Frank and conceived by Francesco Garutti, will follow bplus.xyz (b+) as they establish a policy lab, HouseEurope.eu, to propose industry reforms and shift cultural norms. To Build Law will closely observe the b+ team during various phases of conceptualization and development of a European Citizens’ Initiative meant to incentivize renovation over demolition and new construction. Through this bottom-up legal tool, architecture becomes an open process of establishing partners, drafting legislation, filming stories, strategizing communications, coordinating campaigns, collecting votes, and building a movement.
