The PSI Tower skyscraper is one interesting idea conceived by British Hong Kong-based designer Michael Young, where this conceptual office complex complete with luxury apartments will target business users and executives while overlooking the Kowloon district. This project which is based visually on the essence of ancient Chinese building techniques, will feature a multi-faceted surface which can change according to weather and light conditions. Basically, tts hexagon-studded shape will feature various faces that can move to maximize the amount of natural light flowing into the structure which will in turn reduce the amount of electricity required to light up the building.
