The journal, Building Design and Construction observed of Lotte World in 1989: "The new Lotte World complex located 15 minutes from downtown Seoul in Jamsil Korea, has the largest single glass skylight in the world, according to its manufacturer, Super Sky Products, Inc. A vault with half-dome ends, the skylight is 680 feet long and 197 feet wide and covers an open area of 134,000 square feet. It is glazed with 1 5/16-insulating units consisting of an outer light of 1/4-in. tempered Solex with a low-E coating on its inner surface and a 9/16-in. clear, laminated, heat-strengthened inner light. The skylight has a total glass area of 150,000 square feet, made up of about 6,000 lights of glass." The elaborate daylighting effort was for one of the largest shopping malls built up to that time in Korea. Lotte World contained 350 shops and two large department stores. Added to the mall complex was a 33-story hotel with 535 rooms and an enclosed amusement park occupying 20 acres. (See "Skylights, space frames expand design options," Building Design and Construction, vol 30, no. 3, 03/1989, p. 92.) An Irvine, CA-based architecture firm, Battaglia Associates, designed this shopping/entertainment complex.
