Intent
The hood is treated as part of the wall architecture: a simple volume with enough weight to anchor the elevation, finished to relate to the backsplash without imitating slab stone or concrete.
Coordination
In a built application, the finish is downstream of ventilation performance, clearances, framing, substrate rigidity, access panels, heat exposure, edges, and interfaces with cabinetry and countertop materials.
The goal is continuity without concealing the practical requirements that make the assembly serviceable.
