The architectural design of the LG Arts Center goes beyond the conventional box shape and incorporates natural elevation to evoke a futuristic feeling. The stainless steel, glass, and granite exterior corresponds to modern image of the urban architecture while the interior, finished with natural brown colors of wood and soothing blue, resonates warm and welcoming atmosphere to the audience as both a public space and artistic setting.
The undulating ceiling highlights the main lobby where box office, coat check, and snack bar are located. The theater and the seats are located above the main lobby and can be accessed by escalator and foyer stairs. The theater houses three levels of seats; orchestra level, first balcony level and second balcony level. Each floor features waiting areas, restrooms, and a snack bar to accommodate the audience. The glass windows are draped with contemporary style metal curtains, and they offer a refreshing view of the Yeoksam area during the day and create a unique scene along with outside lights during the night. Inside the theater, the royal blue colored seats are meticulously designed and arranged to ensure best view for each member of the audience. The temperature control system is placed beneath the seats to circulate fresh air while totally blocking out noises.
