The Council on Tall Buildings and Urban Habitat defines a twisting building as one that progressively rotates its floor plates or its façade as it gains height.
[2] Turning Torso, in Malmö, Sweden is regarded as the first twisted tower or building.
[4] When completed, Diamond Tower will be the only building to twist a full 360 degrees along its height.
F&F Tower, in Panama City, holds the record for the tightest twist, that is, the highest average rotation per floor, at 5.943 degrees across each of its 53 floors; and as of 2017, it is the completed building with the highest total rotation, with 315 degrees.
