The Korea Gas Safety Corporation project was conducted using a technical proposal and bidding process. Most government agency relocation projects require eco-friendly design and energy conservation (window-to-wall ratio of 40–50% or less) as basic conditions. They generally avoid layouts featuring an imposing central plaza at the front that disrupts the urban flow and a main building at the rear, instead prioritizing layouts that maintain continuity with adjacent street-facing buildings. To express the Corporation’s top priority—gas safety—in a straightforward manner, stable horizontal elements were established as the facade concept for each building. In particular, while aiming for a window-to-wall ratio of 40% or less, eco-friendly elements such as wind catchers and sunshades were incorporated into the facade design to move away from the rigid image of perforated windows.
