„Ar de Rio“ is the newest of a number of bar pavilions situated along the banks of the Douro with a view towards the historic city center of Porto. All pavilions follow the basic principle of minimal use of design elements and simple means of construction. A new addition for „Ar de Rio“ was requested, which resulted in the development of a new kind of pavilion module. Its structural system, a frame made of honeycomb-like welded steel panels, spans the length of the module and creates a frame for the sensational view towards the river and the city.
