Casa da Levada is a sustainable private house in Penafiel, northern Portugal, designed to merge with its rural surroundings as if sculpted by nature itself. Inspired by the slow erosion of water over land, the architecture follows the terrain, establishing visual and physical continuity with the landscape. Built with natural cork, local granite and timber, and organised around a central courtyard, the house integrates passive strategies and low-impact materials to achieve thermal comfort, spatial simplicity and environmental harmony in a timeless, rooted architectural gesture.
