In the title compound, C19H30O3Si, both rings adopt a half-boat conformation. Overall, the mol-ecule approximates a U-shape as the cyclo-2-ene-1,4-dione and butyl-dimethyl-sil-yloxy substituents lie to the same side of the central cyclo-hexene ring; the methyl substituent lies to the other side of the mol-ecule. In the crystal, linear supra-molecular chains along the b axis are sustained by C-H⋯O inter-actions.
