The paper suggests a possible systemic interaction with the built environment that is to lead towards its
transition to Post-Anthropocene through cross-species co-living oriented governance. Today, governments across the world, such as Czechia, UK, Norway, Turkey, Canada or US are releasing strategies and programs for climate adaptations, discussing weather, biodiversity and food security (Czech Republic Ministry of the Environment & Czech Hydrometeorological Institute, 2015; Department for Environment Food & Rural Affairs (DEFRA), 2018; Flæte et al., 2010; Republic of Turkey Ministry of Environment and Urbanization, 2012; Richardson, 2010; U.S.Department of State, 2014). The paper exemplifies and seeks for systemic relations and reflections of gathered documentation of breathing walls, envelopes and screens that are generating bio-climatic layers in the built environment. The diverse study journeys samples that were co-designed through vernacular culture and the author’s own research by design speculations are investigated and speculated upon through gigamapping. Gigamaps are devices for design inquiry rather than analytical tools like those used in systems engineering or in hard systems models (Sevaldson, 2018). Accordingly, this Gigamapping is not to present any hard data model but to inform and speculate on the investigated field that is grounded in research by design on cross-species co-living in built-up environment through possible architectures and architectural and urban design parasites transitioning towards synergetic landscapes of our envisioned futures.
