Korean architectural firm JOHO Architecture has designed the Curving House. Completed in 2012, this 2,005 square foot contemporary house in Gyeonggi-do, Korea, is lifted from the ground and features a curving shape which resembles a concave lens. The mountains penetrate the sky and the sky contains the mountains as nature. Here, the mountains form lines and the lines remember the mountains in the land. The terrains of Mt. Gwanggyo flow low above the lot and the lot displays the entire view as if it responds to the graceful flow. he traditional bricks used for this project have silver water-repellent coating on the surface and show sentimentality different from the rough surfaces of their tops and bottoms. The bricks with two different surfaces were piled to form a certain pattern from angles 1° through 25°. In other words, the variation of angle is another way how the outer skin in the shape of a concave lens facing south defines its existence. The staircase to the north is planned to serve as a buffer of air against the freezing northwestern winds in winter to minimize heat loss. The front windows facing the south allow sufficient sunlight in winter to maximize energy efficiency with natural sunlight. In particular, the ceiling is also diversified to invite as much natural light as possible into the building to control illumination naturally.
