The water's shore, used for defense, trade, transportation and industry, always plays an important role in a city's development. Buildings were built there to fulfill related practical functions, such as barns, factories or piers. However, at the present time, the functions mentioned above are not the only purpose of the shore, now more entertainment activies happen along the water's edge. Therefore, architecture's roles are changing. The site is in a small town called Riva San Vitale, which is located at the south end of Lake Lugano, Switzerland. For this small town, lake's shore is usually used by local people as a place for relaxation. Based on my four-month long living experiences there, I decided to design an art center on the lake to enrich residents' daily life. / Master of Architecture / A folding method was used in form processing to reflect the mountains' shapes surrounding the town. Through this whole process, my thesis explores how the architecture is used as an instrument to bring art into people's daily life and, at the same time, extend people's life into nature. As a result, the Art Center will become a new plaza of Riva San Vitale.
