Starting with a mist-harnessing prototype, the project was developed through atmospheric experimentation, coded drawings and iteration leading to the final proposal of a weather-responsive bathhouse set in Elmley’s fragile ecological and social context. A drawing methodology alongside analyses of iterative test bed models simulated mist movement. As the project unfolded, the architectural outcome became uncertain, highlighting the need to think beyond architecture, building on earlier coded drawings. Mist was the central ingredient, not only controlled but designed alongside, curating spatial and atmospheric conditions. In a process of blurring the line between designing rigidly for the programme and following the natural results of test bed research, an organic and unique building design emerged. Grounded in the landscape, Elmley Bath House offers bathing experiences that connect visitors to the shifting weather and environment. It incorporates circular systems: harvesting rainwater, generating tidal energy, and reviving salt marsh ecology. In a context marked by erosion and isolation, the architecture promotes restoration and reconnection between people, climate and land.
