Non-orthogonal high-rise buildings are emerging with an increasing degree of geometrical variation. As yet no scheme categorises data on the basis of the overall geometries of such buildings. The author proposes an easily accessible morphological scheme which for example, nables data to be retrieved on sustainable performance of the distinctive building shapes or façade build-up.

The shaping of most non-orthogonal high-rises is related to developments in modeling software. The morphological scheme is based on software manipulations to describe shaping, not on mathematical formulae. As software develops, new ways of generating and new shapes emerge. In onsequence the shaping scheme gradually will be updated. The scheme is illustrated by examples of overall shaping and materialization trends.
