Scotland’s largest city and the United Kingdom’s third largest, Glasgow was a major shipbuilding port and industrial center. This urban past is honored in the Riverside Museum, raised at the confluence of the rivers Kelvin and Clyde, a spot once busy with the construction of packet boats, ferries, and cruisers. Open at both ends, the museum stretches like a sinuous ribbon, almost a tunnel, tying the city to the riverbank. Objects of different scales are contained in a fluid interior that rises high and has no pillars. The winding ribbon which mirrors the flow of the water is manifested in a fluted skin crowned by two gable ends with stepped sections. Executed with precision, the skin is multilayered: from inside to outside it is formed by a ceiling of undulating galvanized metal sheet and a steam barrier, insulation 200 millimeters thick, a 100-millimeter plywood with bitumen primer, and cross-seam panels of zinc 0.8 millimeters thick.
