Elenberg Fraser’s tallest building will add a twisting kaleidoscope that seems to defy the laws of physics to the North edge of the city.Appearing to turn on its trajectory, the building has no corners. How do you dissolve the corners of a skyscraper when that is where all sheer forces are normally resolved? Well, we discovered the answer lies in traditional masonry techniques for turning corners using bricks. This three-dimensional kaleidoscope not only twists and undulates on its axis but its façade is a moving object. The effect of constant motion is amplified by the multi-chromic directional paint system applied to the surface, which reflects and draws the building up into the sky. You may have seen this paint effect on cars before, but never on a building!This supermodel of a building also needed to battle the slenderness ratio – the rule that governs how tall and thin buildings can go. It overcomes this constraint by virtually becoming a vertical cantilever with a series of outrigger beams to prevent it from overturning, and to stop it rotating along with the façade system. The series of rotational units are a series of bay windows for the apartments, which pick out different vistas of city as the façade crinkles.Complete with its own ‘Harry’s Bar’ on Level 1 (minus the $35 bellinis), this 60 storey residential CBD skyscraper is unconventionally extraordinary.
