Synanthropic Habitats originates from the interdisciplinary quest on ‘how will we live together’ and the personal fascination to critically question the deeply-rooted anthropocentric binary of human (us) and nature (them). The thesis aims to establish an innovative domestic environment that deals with the heterogeneity of people of different backgrounds while reflecting upon the global urgency of the Anthropocene by interacting with nature in a blended game of cohabitation. The project forms its wider problématique from an amalgam of constituent problems deriving from Rotterdam and specifically Blijdorp as the site under investigation. The high traffic lane that dichotomizes the site, the noise and pollution of the nearby railway station, the large undefined spaces in tandem with the prevailing social degradation, and the need for affordable housing provision are a few of the identified issues of the project’s location. As a response, the Synanthropic Habitats attempts to develop a new paradigm for Dutch housing design, based on the triptych of hofjes as a type, thresholds as interfaces, and cooperatives as nomos. The project draws from the long tradition of Dutch hofjes as an archetypical sustainable domestic milieu, the epistemologies and multiscalarity of threshold as a key tool to create zones of encounter, and the non-speculative forward-thinking model of cooperatives to shape a framework within which a multi-storey building with integrated nature, a variety of households and common spaces will flourish. Towards that direction, literature research on the topics, typo-morphological analyses of relevant precedents as well as in-situ observations are employed as methodological tools to conclude in spatial and theoretical aspects contributing to an ecology of inclusion in the design. Utilizing and revisiting the pre-existing type of the hofje, inflected with the threshold character of commons creation and the pragmatic scenario of devising cooperative tenure generate an evidenced-based dwelling design that is as much of a site-specific architectonic product as a universal proposition to be adopted across contexts.
