ATEC's office building was designed as a building with a distinct character that would blend in with the other office buildings to be constructed in its vicinity. The façade was simplified to express the physical properties of the stone material more massively. Patterns of varying sizes and depths were applied to the façade to balance the surrounding context. ATEC's office building is rationalized with minimal use of finishing materials and design language. It will open a new era of IT in Pangyo.
