The project deals with the revitalization of the existing ‘HL green building’ with a new fabric of urban programs creating a sense of community but keeping in check its carbon emission in the process. The main concept of this design is to create an open and free-flowing circulation within its rigid existing facade by introducing an open courtyard. In addition to forming a space for social interaction, the open courtyard space intertwines various programs creating a seamless visual and physical connections between the exterior and interior spaces.

The central courtyard space acts as the breathing node connecting various programs and this organic space which is formed runs across levels naturally ventilating throughout the building. The primary circulation includes two massive ramps connecting the basement and mezzanine, which is both utilitarian and function. A series of external stairs are placed around the open court space to imbibe the nature of its surroundings and provide a breakout space for its users during circulation.
