In understanding the concepts of permanence and transience, this piece of architecture on the beach carries an instrumental quality of measuring the observation of the sea as well as the time lapse of human activities at the beach. The structure’s overall form is defined with three circles that change in radii and positions. The individual pieces take on the forms of changing shapes of triangles that endow spatial compression and expansion, and are pre-cast concrete that bear the quality of being the permanent elements at the beach. As the main function of the piece is to observe the sea, the distance between the individual pieces decreases as the viewers approach the sea, rendering a gradual procession from group to individual observation. The back of the structure performs as a life-saving station that include secondary wooden structures that allow for the impermanent inhabitation and suggest the potential for future redefinition of the functionality of the space. The eventual result of the piece becoming the remnants of human civilization will act as a monumental reminder of the constant-evolving meaning of human relationship with the ocean.
