Two buildings, one rule. Both are built from a single 6.000 m member repeated without variation, and both stand on the same 10.208 m base. Nothing was re-proportioned between them: the second is what the first becomes when the icosidodecahedron is expanded — its twenty triangles and twelve pentagons pushed out from the centre and the gaps patched with a square per edge. Doubling the vertex count multiplies the usable floor area by 3.09.
