On the coast to the south of Rio de Janeiro, a leaf-shaped home rises out of the Brazilian landscape like a work of nature. Casa Folha by Mareines and Patalano is a large tropical shelter housed under a roof that is shaped like a complex leaf. Its six sections contain a large central atrium, a two-story open patio and a few sections of private and shared space within. Its interior is as naturally-inspired as the leaves above, with fine wood floors and walls with earth tone accents in draping and furnishings. The lighting of Casa Folha is quite remarkable, as hidden lights do much of the work of bringing out the home’s true character at night. While it may not have the contemporary focus of most of our coverage here on TheCoolist, this work of architecture by Mareines and Patalano is decidedly cool in its own right.
