Constructing a cantilever structure is one of the most difficult things for a structural engineers to do. Remember the thumb-rule – for every foot cantilevered, you must anchor it at the support to a depth of 1.5 feet. For an architect, cantilevers are beautiful things and can literally extend capabilities of their building while remaining beautiful. They offer limitless opportunites but are beyond the technical capabilities of architects to maximize their utility completely. This struggle between the structural engineer and the architect has always been fraught with compromises and hence mediocrity in design. That’s why it is a refreshing change to see structures that push the envelope and exist in defiance to all logic:
