This amazing house in Rio de Janeiro, Brazil – inspired by Brazil’s Indian architecture. The Leaf House was designed by architects Mareines +Patalano. The creators of this eco wonder – a quite good job to maintain the harmony between man and nature. The house features a roof shaped like a giant leaf – the large roof provides for spacious verandas and large interior open space that allows trade winds from the sea to pass trough the building – this is natural ventilation. It was built using by organic material and includes a design to harvest rainwater for re-use.
