Spiral staircase (metal frame and glass steps) PARK STREET SS 423
SPIRAL Stairs
The only part of this stair that touches the floor beneath it is the centre pole and even that flows through the glass. The first tread and handrail are supported by a cantilevered arm off the centre pole because the glass floor’s integrity would have been compromised by fixings. The glass floor panel lets light into four flight stairwwell below.
