A great deal of effort has been taken to conceal this primary structure and hence direct the observer’s attention to the three-dimensional steel-and-glass vista. Besides the elaborate pavilion, seele is also responsible for the keen lines of the highly aesthetic “architectural steelwork” framing the façade at the base of the tower ‒ the three bottommost rows of panes fronting the lobby. Large-format insulating glass units measuring 3m x 5m or 3m x 6m are being used here.
Only the glass and the precision silicone joints are visible from outside. The result is a homogenous surface without any external fixing elements. The glazing to all four elevations at the base of the tower adds up to 3,600sqm and is in the form of a steel post-and-rail façade with laminated safety glass. Autumn 2015 saw the start of seele’s erection work on site. Completion of that work is expected in 2017.
