Conceived as an industrial parametric façade system, this project evolved into a conceptual intervention for a district within Tehran's Ekbatan complex — one of Iran's most iconic brutalist housing landscapes. The idea is not to correct raw concrete, but to let it breathe: a living skin of bio-receptive louvers, drawn algorithmically from sun path and prevailing wind, settles onto the existing structural frame like green veins traced across aging concrete — adding no load, blocking no view. Across its porous surface, native mosses take root, without irrigation, without intervention. This living membrane filters pollutants, cools the façade through evapotranspiration, absorbs the city's noise, offers privacy while keeping the skyline visible, and gives brutalism's silent monumentality a second, breathing life. Rooted in UN SDGs 3, 11 and 13, the project is less a technical retrofit than a quiet narrative of renewal — proof that a weathered building can live again.
