My personal interests and professional work of scope in architecture have been about how to better create landmark building for cities. The basic characteristic of landmark is that people can use the simplest form and a minimum of strokes to evoke the memory for it. Just like the Pyramids of Egypt, Opera House of Sydney, Temple of Heaven in Beijing, Empire State of New York, and many other famous landmarks in the world, they become a symbol and business card of the city.

By compare and contrast their individual relationship to the local culture and building environment, we can better understand the reasons behind their success and failure.

The building façade is made of different folding planes, reflecting the changing surroundings in a harmonious way. Unlike traditional office buildings with regular 90-degree lines and traditional divisions, the tilting planes of the façade create a more intimate and unique scale. At different time depending weather of the day, the various reflections also add a touch of elegance to the building. The gesture is strong, but not overwhelming; the reflecting planes are complex looking, yet still sensitive to the historic architecture of Victoria. Giving the complex outer shell, the structure of the building is extremely challenging, resulting efficient floor plans and spatial arrangements. On the lower level, inward-ti
