简介:这座低层住宅是在一次建筑改造活动中设计的,于近期完工。业主希望能够最大化土地的利用率,并且希望住宅是生态的:其次是内向性的空间,以便保护隐私;最后业主希望能够引入周围山体的景色,以便在卧室能获得非常好的视角。住宅本身要具有韩国文化的印记,建筑师解决了内向性空间以及生态环境的设计,将室外空间的使用率提高,营造一个健康、自然的生存环境。同时吸取了山体周围环境的多样性和独特性,将卧室通过轴线引入到山体景观中,架空层是住宅多样性序列空间的开始,就像是一个地窖。建筑师将传统建筑语言转换为现代建筑语言,通过椭圆形的图案来装饰墙面,这源自于传统的石墙。住宅室内外通过一个回旋式的路径来创造一个多样的空间,建筑师希望业主的生活能够通过这个回旋式的空间而变得更有趣。
