We could not find the buildings that exactly repeated the parabola formula, but there is a skyscraper in London (United Kingdom) with a very unusual shape. The Mary Eks skyscraper referred to by locals as the Cucumber (or the Gherkin), has no corners, which prevents the wind flow from flowing down and provides natural ventilation. The height of the 41-story building is 180 meters. The building's diameter at the base is 49 meters, which then expands smoothly, reaching a maximum diameter of 57 meters at the level of the 17th floor. The design then narrows, reaching a minimum diameter of 25 meters.
