Stone executed at architectural scale
Every project on this page was supplied from our own quarries, fabricated in our own facilities, and delivered to site without intermediaries. Volume, continuity, and provenance — verified at every step.
Three sectors. One supply chain.
Five-star hotel lobby and corridor
2,400 m² of Statuario marble, sourced from our Carrara quarry. Slabs selected and matched on-site at the facility. Fabrication, logistics, and installation support fully internal.

Every project documented — quarry to installation
We document stone origin, block reference, fabrication scope, and logistics chain for every project. Architects and developers receive full material traceability — not a certificate, a verified record.
Quarry-referenced blocks
Scale without batch inconsistency
CNC, carving, logistics — internal
Processing, CNC profiling, custom fabrication, and freight coordination are all handled within SPI — no subcontracted scope.
Each slab carries a block reference traceable to a specific extraction face in our Italy, Portugal, or Spain quarries.
Direct quarry access means large-volume orders are matched to a single geological vein — no colour drift across phases.
