Sydney Just Opened a 42-Metre Steel Lookout Over a Former Quarry - Yanko Design

"The Southern Lookout at Hornsby Park in Sydney is exactly that. And it is worth every bit of attention it's getting. Designed by AJC Architects in collaboration with Clouston Associates, the structure sits on the northern edge of Sydney, overlooking the dramatic topography of Hornsby Quarry. The site itself has a remarkable backstory. For over a century, the quarry was completely inaccessible to the public. A place that had been carved out and worked, left to become something between ruin and wilderness, invisible to the city that had grown up around it. The Southern Lookout is the first completed architectural piece of a much larger 60-hectare landscape masterplan. It is, in the most literal sense, an opening."

"The choice of weathering steel is the first thing that makes you stop and think. Cor-Ten, as it's commonly known, is a material that rusts deliberately. It forms a stable oxidized layer on its surface that protects the steel beneath while giving it that signature warm, amber-brown tone. It is a material that ages visibly and honestly, and for a project like this one, placed on the edge of a quarry whose story is entirely about time and transformation, it feels less like a design decision and more like a point of view."

"The platform runs 42 metres through the forest canopy, anchored into the embankment and balanced on four angled columns that converge on a single central footing below. That minimalism is intentional. The architects worked specifically to keep ground disturbance on the sensitive slope to a minimum. The result is a structure that feels both bold and careful, which is a hard balance to get right, and one AJC Architects manages convincingly."

A 42-metre platform made of weathering steel spans the forest canopy at Hornsby Park in Sydney, suspended over Hornsby Quarry. The structure sits on the northern edge of the site and overlooks dramatic quarry topography. The quarry had been inaccessible to the public for more than a century, remaining a ruin-like landscape hidden from the surrounding city. The lookout is the first completed architectural element of a larger 60-hectare landscape masterplan. Weathering steel forms a stable oxidized layer that protects the steel and develops a warm amber-brown tone as it ages. The platform is anchored into the embankment and supported by four angled columns converging on a single central footing, keeping ground disturbance minimal on a sensitive slope.
