The fireplace wall is conceived as a monolithic volume resting on a continuous mineral plinth, ensuring structural clarity and anchoring the entire composition. Steel-framed grid doors introduce a strict modular rhythm that extends visual axes, while reflective panels amplify depth and distribute light uniformly across the floor plane. The kitchen island—fully cantilevered on its base and finished in high-density stone—establishes a technical counterpoint to the soft geometry of the helical staircase, whose seamless balustrade expresses pure volumetric continuity.
