Annatto, red in Tupi-Guarani, also refers to a plant native to the Amazon region that is used as a dye. The term influenced architect Vanessa Martins Miranda and her partner, Eduardo Miranda, in the design of this 71 m² house, which seeks to honor Brazil's indigenous heritage in vernacular architecture. The vault is reminiscent of a hut, the woven pattern of the wooden ceiling evokes artisanal techniques, and the reddish granite highlights the wealth of natural resources. The stainless steel volume represents a futuristic vision of innovation and progress.
