Becoming one with mother nature has been taken to new heights. Thanks to the architectural firm ATV Arquitectos, complex multi-family housing looks as attractive as it sounds. Recently building an enormous marino house in the heart of Argentina, the Buenos Aires-based company made sure the residence was surrounded by towering pine trees in a creative manner. Covering 350 kilometers, the concrete and wood construction hosts two stories that are full of adventure and comfort. Mixing privacy on the upper levels with an organic connection on the ground floor, you can always find your escape on the observation deck. Enjoy the gorgeous photo gallery above.
