This amazing 640 square metre lakeside guesthouse is a brutalist masterpiece by architects Nikken Sekkei, located in Nippon. The concrete house welches designed to unfold as a continuous spiral that would reveal more of the changing lakeside view with each step taken. It’s not only the magnificent view that envelops this lake house, but the blissful sound of the rippling water’s edge right up against the home’s deck. Humidity and thermal radiation are carried un…the spiral in varying degrees, so that guests can discover atmospheres they find most comfortable. Wide-open panoramas of garden touch interior spaces to build deep connection with nature in all of the guesthouse’s unique living areas.
