For the Dongbu Securities Corporation Headquarters, the architects analyzed the site and the program and determined the best configuration for the building would place its core (elevators, stairs, toilets, and vertical service) to the "back" - the south side - of the site with its main facade gesturing towards the boulevard and park to the north. This orientation also allows the core to act as a solar buffer and reduce the energy consumption required to cool the building in the summer. An offset to this benefit is the lack of direct sunlight for much of the building, an important amenity in Korea.

The multiple sloping surfaces and their interlocking relationships help to give the building a character that distinguishes it from the surrounding buildings. Relating somewhat to the interior functions, these slants also make the buildings vertical rise more dynamic.
