We present a system to procedurally generate complex models
with interdependent elements. Our system relies on the concept of
components to spatially and semantically define various elements.
Through a series of successive statements executed on a subset of
components selected with queries, we grow a tree of components
ultimately defining a model.
We apply our concept and representation of components to the
generation of complete buildings, with coherent interior and exterior.
It proves general and well adapted to support subdivision
of volumes, insertion of openings, embedding of staircases, decoration
of facades and walls, layout of furniture, and various other
operations required when constructing a complete building
