The ocean is vast, boundless, and yet it is mysterious. The knowledge of mankind is just like the ocean, it is limitless and awaiting us to explore. The ocean is also joyful. With the colorful and magical creatures features, the ocean is like a magic box that can give you infinite happy surprise. The design of the library and the Preschool would utilize the colorful characteristic of the ocean to create eye- catching features all round the building that would amuse both children and adults, while the childcare center would use more cartoon- shaped designs to amuse the children, and to build connections between human and nature. Using organic shapes in the building to mimic the waves and the calmness of the ocean, while preventing children from hurting themselves from sharp angles. Create different zones for different purpose in both the library and preschool helps build-up privacy in the building.
