With humanity gaining a level of dominion over Earth, resulting in modifying its entire atmosphere through terraforming (earth-shaping), this leaves serious questions to reassess our way of habitation. Despite minerals on our planet being finite and a circular economy only at 7% globally, the project speculates on the role of architecture in both supporting the environment during ecological crises and by extending the notion of circularity itself. Instead, through a speculative methodology, architecture is seen as a regenerative force embedded within ecological and material systems. 
  
Hereby, the research investigates non-extractive architecture as a means to reimagine construction in ways that do not impose environmental harm. Instead of minimizing offsets and damage, it is envisioned how to foster material economies and social infrastructures rooted in regeneration, stewardship and symbiotic interdependence. Finally, architecture isn’t situated as the end point, but as part of metabolistic processes, enabling it to nourish soil, ecosystems and communities across multiple lifecycles. 
  
Through speculative methods like science fictioning and narrative building, the traditional tool LCA (Life Cycle Assessment)  is shifted from optimizing for efficiency to entanglements (Life Cycle Assemblages). By emphasizing health of entire sites rather than materials, the role of design adopts non-human perspectives to promote futures of co-existence between species in an attempt to foreground a critical lens upon Western society. In the speculative nature, the project combines questionss about the Anthropocenic human state in a utopia where thermal comfort, co-existence and alternatives to the neo-liberal economy emerges. 
  
With other factors such as climate, migration and political ecology, the culmination of the research lies in the act of expanding architectural thinking toward planetary interdependence. Circularity is reframed from economic metric, to a relational ethic, an ecological worldview. This is supported by alternative biogenic materials, a culture shift in the maintenance of the built environment and lastly socio-spatial configurations in which communities take on roles of stewardship rather than extraction. Through this lens, the project envisions architecture as compost: a living, decaying, and renewing practice in service of the Earth.
