Diaphanous Shift: Reconfiguring the threshold Part 2 Project 2025 Charles ThadwaldCallum Salem University of Plymouth | UK This project explores architecture as a responsive, adaptive system embedded within the intertidal edge of Plymouth’s South Yard. Our modular proposal, composed of the Research Hub, Trantor, Unity Spine, and Terminus, operates as a constellation of elements in continuous dialogue with climate, time, and community. Grounded in neoplasticist principles, the design emphasises spatial relationships over fixed form, unfolding through time towards 2100.Developed through collaborative research, our work engages with ecological fragility, historical palimpsests, and future urban imaginaries. Concepts such as chronotope, palimpsest, and diaphanous mutatio guide our speculative yet grounded architectural response. We integrate site-specific data, narrative strategies, and scalable design typologies to confront rising sea levels, shifting socio-political thresholds, and evolving ecological systems.Our approach is underpinned by three key actions: making (prototyping and fabrication), releasing (unlocking spatial potential), and rethinking (reframing architectural roles). This project is both a testbed for resilient coastal inhabitation and a living archive of adaptive urbanism. Tutor(s)
