Thumbs-up building

In Seoul, B.U.S Architecture realised an office building, which maximizes the livable area and features windows that get smaller as they go backward overlooking the Han River.

The first aim of the Thumbs Up Builging by B.U.S Architecture was to maximize the rentable area by securing as much coverage and floor area ratio as possible. Once enough area was secured, the volume was naturally decided, except that some devices were needed to attract pedestrians on the narrow land adjoining the main road. This narrow land becomes a road that is divided into two roads: one for crossing the ground to get behind the building and the other to climb the building and rise into the sky.

The client demanded that all the building sides should be built with curtain-walled windows, but the land was located in an area of no interest, and according to the deliberation criteria, the building had to have a less than 60% of windows surface. The Korean architects modified the sizes of the windows according to the direction in which they were seen from each of the corner faces of the building and accentuated the sense of speed of the panorama. As a result, the windows get smaller as they are going backward from the side overlooking the Han River.
