At the Xerox building in Lisbon, Filstone SPI brings a measured material language shaped by a fine-grained grey granite from Alpalhão. Its compact grain, even tone and restrained visual character make it particularly well suited to a corporate setting, where the architecture calls for permanence, clarity and control. In this context, the stone does not rely on visual excess. Instead, it defines the overall perception of the building and gives the facade a strong institutional presence.

Used in the exterior cladding, Filstone SPI sharpens the building’s geometry while adding durability, consistency and predictable long-term performance. Its clean grey tone sits comfortably alongside glass and the remaining materials, allowing the composition to remain clear and disciplined without becoming cold or impersonal. The overall effect is robust and timeless, with the granite contributing directly to the project’s visual coherence, solidity and sense of continuity.
