Presence of nature. These toilets are located inside of mega shopping mall and its concept is 'Park street'. We want to give some 'park' element in toilet space too. From ground floor, we approche with earth/land element, then pass to river/water element on 2nd floor, mountain/forest element on 3rd floor and finally finish by sky element on 4th floor. We put every toilet its own design keword as [WC01 wild land] [WC02 bamboo forest] [WC03 jungle forest] [WC04 savannah oasis] [WC05 tropical beach] [WC06 whtie moutain] [WC07 green mountain] [WC08/09 sunset sky]. To make people feel this different nature and environment on each toilet, we tried to use different material and various type of plantation.
