What we focused on was a memory of a place. Architecture can be memorized as a place if it becomes an image and a sign. To imprint the L-tree tower as a place, we use a zig-zag pattern on the facade. The corner condition is the most important visual point since the site has two open sides to roads. The zig-zag patterns between the vertical elements add tension and direction to the corner. The distance between the vertical elements increases to the corner, giving fast to slow emotion. On the other hand, the angle of diagonal lines is getting lower to add visual strength.
