Influenced by his Tocantins heritage, veteran architect Cristóvão Bisneto invokes history, architecture and religious festivals to reflect on the sociocultural richness of Tocantins. Thus, for Casa Barco, the architect opts for a conceptual signature and uses the natural landscape as a starting point to compose the space with a view of the lake. The mix of styles appears once again and brings references to modernist eco-brutalism, with pillars, beams and exposed concrete slabs, in contrast to the more natural textures and elements. Visual arts signed by Rogo spice up the environment with color.
