Bubble, BMW Group, IAA 1999, Frankfurt / Main, Germany - FRANKEN\ARCHITEKTEN


“Due to the influence of surface tension, the drop aims to achieve a spherical shape. However, its viscosity, torpidity, atmospheric friction and other external forces prevent this, so that it warps through a slightly oscillating drop into a spherical form.”

Long before sustainability became a fashionable word, at the first BMW trade fair presentation realized by Franken, driving with clean energy from water and the sun was symbolized in the form of an iconic structure: a drop of water. A drop simulation computer program was used to create this shape. The Bubble was one of the first structures in the world which was completely created with digital means, from the design through to construction.

"Parametric design, often linking the contextual with the meta-
phorical, is a
transparent and formal approach to the creation of a narrative archi-tecture."
