The architect Cho Byoungsoo has long spoken of ‘Architecture Towards the Earth’. His works were mostly positioned organically on the ground and in nature, with a simple and concise demeanour. Throughout that process, Cho Byoungsoo explored an architectural element that not only responds to various conditions and contexts but also promotes rich phenomenal experiences: it is a ‘screen’, the third architectural vocabulary. Materials such as wood, punching metal, and expanded metal can be used 1) to transmit or block light, 2) to tie and put complex shapes together, and 3) as exterior materials. However, the screens designed by the architect Cho Byoungsoo do not simply exist as functional elements. The aesthetics of screens is discovered in the quality of space, in which the varying size, colours, and angles of the perforations are delicately tuned.
