The Casa Do Lago estate in Aroeira, Portugal, designed by Frederico Valsassina Architects, is a residential construct on a vast golf course. Features of the luxurious home include a large Koi fish pond that sits evenly with the outdoor pool and a massive terrace that creates a smooth transition between the interior and exterior of the home. Tall stone walls separate the living areas of the home, dividing them into daytime social areas and more private evening areas. Large interior living spaces are naturally lit with the light that shines through windows which stretch from floor to ceiling. [via archdaily] View in gallery View in gallery View in gallery
