The Los Angeles chapter of the American Institute of Architects is actually developing into the one-stop destination for amazing architecture. This time around, the KAA Design Group introduces this Tree House in Manhattan Beach. With lofty Southern Californian coasts to the fore, the unitary house (which obviously is not a tree house) combines aesthetic exteriors with stunning interiors studded with wood, concrete and glass. Appealing to the green-minded, the houses’ eco-friendly aspects are all taken care for with heating and cooling solutions, natural ventilation and exposure. Take a look at these wonderful images that depict some real spacey rooms with fireplaces, living rooms, bedrooms, spas or study rooms. {via}
