Rammed Earth and Stone Public Toilets: Low-Carbon Materials and Local Construction Methods

Design a public toilet built from rammed earth and local stone, using low-carbon materials and regional craft. Show thick rammed earth walls with the horizontal lift lines of each compacted layer clearly visible, their colour varying subtly between lifts as the soil changed, and a lime stabiliser giving a slightly chalky surface. Detail the base as a course of local stone rising 600 millimetres to protect the earth from splash, laid with a deep raked joint. Show the roof as a generous overhanging structure of timber rafters and metal sheet, projecting far beyond the wall face on every side because rammed earth must be kept dry — the overhang doing the protective work rather than a coating. Detail the openings as deep reveals showing the wall's full thickness, with a stone lintel and sill. Show the interior lined with a smooth lime plaster for cleanability, contrasting with the raw earth outside. Set the building in a dry landscape with grasses and low shrub. Show low warm sun raking across the lift lines. Photorealistic, earthy, warm ochre and stone, three-quarter view.
