This ribbon is formed of a doubleskin steel surface, the side wings of which vary in size, rising and curving, echoing the static scheme and responding to the direction of gravitational forces. Instead of a raised mass, a concrete continuum floating on the lake’s horizon, here we see a steel leaf framing empty spaces through which can be seen the ever-changing play of light. The double curvature of the steel sheets draws on techniques from the shipbuilding industry, the metalwork of the arches evoking another kind of floatation.
