For the second phase, we need to refine the appearance of tree house and sculptures, and this can be done either by paving mosaic pattern or by painting. The mosaic tile we used for the decoration is all from the recycle pile, we then cut the tile into smaller pieces. We also peeled some barks from a fallen tree and use it as the waterproof skin for the tree house.
After we finished our individual pieces, all of us start to work on the central plaza. Considering this space will be heavily used in the future, we decide to pave the whole place with blue stone slates. Since the ground surface is not even, we have to do the paving after adjusting the existing topology. The process of adjusting and paving actually run back and forth several times caused by the estimate of error with our measurement and calculation, but we did it after all.
