How to model evolving architecture

Hello world,

I am curious to know whether it is possible to model evolving geometry (a very simple cube, for instance), evolving over a period of time according to growing patterns specified before. For example, a cube out of which new cubes grow out and enlarge it or are attached to it, whose specific placements are not specified more than by a series of predetermined rules on how the initial cube can grow/evolve.

It it possible to do this with Grasshopper, and in that case, how is it possible to model the evolution over time; is there a need of specific plugins or settings?

Thank you very much for your help, I´d appreciate every answer that can help!
