This paper revisits the notion of porosity, exploring its terminology, history, and meaning in architecture, positioning it as a transformative design strategy to address the escalating challenges of the climate crisis and challenge the binary notion of habitability. Porosity is examined as a fundamental architectural language, fostering interpenetration and collaboration with inconstant environment. The distinction between porosity and transparency is explored, with a focus on the former’s spatial extension and adaptability to environmental forces. Case studies of the Mountain Pavilion by Peter Salter and the Public Condenser by Muoto illustrate porosity in practise, showcasing a porous structure as a climate-responsive approach in real-life scenario. These cases exemplify responsive architecture that adapts to natural forces and occupancy. Porosity challenges traditional façade roles, proposing an interiority that intricately connects architecture with its context. Informed by Object-Oriented Ontology, the paper envisions architecture as a mediator between human and non-human elements. Emphasising the underestimated potential of a porous architectural language, this study advocates for transformative design methods, fostering a dialogue between environmental shifts, biodiversity, and human habitation. The discussion prompts vital considerations for inclusive approaches, inviting non-human agencies into architectural practises.
