“INSIDE-OUT” is a structure design based on modularity and mobility, divided into two ; a permanent structure and transient modules, one is to serve the floating villages by spreading the modules, one is to allow the modules to move freely around the lake. Occasionally, those modules will return to the permanent structure\for service and maintenance. Besides that, each module is easy to construct and less time consuming due to the usage of the materials and bolting system used for connection.
