The design celebrates a clean, industrial-meets-organic aesthetic. A robust, black coated mild steel structure provides a sharp, graphic silhouette, which is softened by the warmth of solid oak treads. These timber elements are precision-engineered ensuring durability and safety without compromising the minimal palette.

Capping the structure is a continuous, contoured oak handrail that follows the fluid curve of the steel balustrade, offering a tactile transition as users move between floors. More than just a circulation route, the staircase acts as a central focal point, grounding the open-plan interior while providing a transparent, light-filled connection that enhances the flow of the entire fit-out.
