The project transforms an existing semi-outdoor transitional space into a civic square for the members of the academy, in the name of Professor Charles Kao, the pioneer of the development and use of fibre optics in telecommunications.

The design concept is to construct a pavilion under the sky where students, teachers and visitors gather. Two-layered glued-laminated timber beams are used to construct the spatial structure, with directions echoing the spatial connections linking the key spaces. They become lines guiding people across the square.

Lighting is essential to create an uplifting atmosphere in such a deep space. To achieve this, above each timber beam inserts a continuous line of light boxes. Each light box is made of LED strip light with stretched barrisol membrane below to diffuse light uniformly like the sky.

The design delibrately replaces the wall of the library with a stage to create a smooth transition between the square and the library. Informal and formal performances, sharing and talks can take place. Existing staircase to senior common space on floor above is enlarged to create a hang-out steps where members can sit and relax next to the lush hillside. Cafe is connected to the square with seating spilling out, and the existing courtyard is enclosed and framed to appear an internal garden for the square.

The whole space becomes a vibrant space with various activities can take place.
