The two-floor building is divided into two cuboid volumes, one of which on the second floor is rotated counterclockwise. The upper building volume is separated from the original structural frame, with the intention of turning it towards the main entrance of the whole site to present an open and friendly gesture. Expanded aluminum sheets and steel structural components are made of environmentally friendly materials such as aluminum and other metals. The materials are reusable, safe and secure, and will not change color or rust, which will save a lot of cost at the same time.
