A structural fusion of stone, glass and steel
This staircase provides a high-end circulation solution that maintains the bright, airy feel of the surrounding space.
It’s a sharp dog-leg configuration, supported by a precision-fabricated steel channel structure and to keep the design feeling lightweight despite its robust engineering, the intermediate landing is suspended via architectural box-section hangers opening up the floor void below.

The aesthetic is a balance of natural stone and industrial accents. Each tread is finished with aa Crema Perla stone overlay, a material chosen for its warm, fossil-rich character, and punctuated by stainless-steel inset nosings for added definition and durability. The clean, horizontal lines of the stone are mirrored by the sleek metal panelled soffit on the underside, ensuring the staircase looks as refined from below as it does from above.
Frameless glass balustrading runs the full length of the flights and extends across the floor voids, maximizing the flow of light and maintaining clear sightlines. A continuous timber capping handrail provides a warm, tactile touchpoint, tying the modern glass and steel elements back to the natural tones of the limestone. The result is a highly functional core that feels like a seamless extension of the architecture.
