The geometric forms of Unexpected Hill are inspired by 2D ceramic patterns found in architecture throughout history. Sevince Bayrak, co-founder of SO? Architecture and Ideas, explained:

“We manipulated a geometrical pattern of triangles to create a 3D form. As an example of using geometry to convert a 2D object into a 3D space, the structural principles of Muqarnas help us create a hill, the highest point of the 3D structure, which will be a tunnel that visitors can pass through.”
