Murphy Schmidt Solicitors
Free standing zigzag stair.
Murphy Schmidt Lawyers Offices Fit-out Project (2006) 130 Mary St, Brisbane.
Installed within the original masonry of this colonial Brisbane building but not reliant upon it, this stair gains support from a hidden structural frame fixed to the concrete blade rising through the centre. Using hidden structural steel, the zigzag timber structure looks like a solid Jarrah block extruded from the concrete column. The stair links what was an original basement but now a partner’s chambers through the ground floor reception to the upper floor offices. The glazed balustrade continues around the central void edges based on the massive original structural timber beams of the building contrasting the old and the new.
Stringer Construction: Commercial grade laser cut 12mm plate steel zigzag non-visual stringers clad with pre-finished solid Jarrah panels and soffits (PS2)
Treads: Manufactured pre-finished select grade Jarrah tread/riser assemblies with rebated 33mm Latham 322S “Sparkling Black” non-slip nosing strips.
Balustrade: 12mm cantilevered clear toughened glass panels supported via 38mm stainless steel through glass patch fittings attached directly to the hidden steel frame and Continuous 38.1mm CHS stainless steel handrail. (PF10).
