Weathering steel remains a prominent material in architectural design, defying any predictions of its decline. A collection of projects completed in 2025 underscores its enduring appeal, showcasing its versatility across various applications, from industrial headquarters to residential structures and artistic installations. Its distinctive patinated finish and robust nature continue to captivate designers, offering both aesthetic depth and practical benefits.
One notable example is the EMIT Technologies headquarters in Wyoming, USA, designed by CLB Architects. This project involved the custom fabrication and on-site engineering of almost all the weathering steel cladding. The choice of material for this energy and manufacturing company's base, which transformed a former Kmart, speaks to its industrial heritage and durability. A perforated scrim layer of the same material provides shading while subtly revealing the internal activities, blending functionality with a unique visual texture.
Similarly, Neri&Hu's "The Yard" in Dalian, China, is an adaptive reuse project that transformed an old industrial complex into a vibrant creative hub. Corten steel, the original brand name for weathering steel, was extensively used as the primary surface material. This selection pays homage to the site's rich industrial past, allowing the building to age gracefully and integrate seamlessly with its surroundings while reflecting a sense of history.
Further demonstrating its robust qualities, weathering steel was chosen for the Nujiang River 72 Turns Canyon Scenic Area in China by Archermit. Its exceptional durability was crucial for this cantilevering viewpoint over the Nujiang Grand Canyon in Tibet, which experiences extreme weather. The material's rusty tones echo the rocky landscape, and its color holds cultural significance in Tibetan traditions. The structure features a reinforced glass floor, offering visitors a breathtaking view of the river 130 meters below, embodying both strength and an immersive experience.
For residential applications, Prospect Studio's Alta North Residence in Wyoming, USA, exemplifies weathering steel's popularity. Situated at the edge of a forest, the design sought to create a structure that was both visually striking and deeply connected to its environment. The steel was combined with concrete, reclaimed timber, and stone, alongside cedar-lined soffits, to achieve a harmonious blend of materials that respect the natural setting.
Balkrishna Doshi and Studio Sangath's Doshi Retreat in Germany represents the late Pritzker Architecture Prize-winner's final project. This contemplative structure, located on the Vitra Campus, uses weathering steel crafted from recycled materials. The choice reflects the material's ability to evolve in appearance with changing weather, imbuing the building with a sense of vitality and continuous transformation.
In Knoxville, Tennessee, USA, Sanders Pace Architecture utilized porous Corten steel panels for the Baker Creek Pavilion. Located in a park next to a mountain-biking track, the pavilion was designed to be sturdy yet minimally intrusive to the scenic views. The low-maintenance aspect of the material was a key factor, ensuring longevity and reducing upkeep requirements for the public space.
Paul Cocksedge's "What Nelson Sees" in Trafalgar Square, UK, incorporated weathering steel into an artistic installation for the London Design Festival. This sculpture, created to highlight Google's AI tools, featured metal tubes that functioned as viewing portals, projecting AI-generated films of London's past, present, and future from Admiral Horatio Nelson's perspective. The raw, industrial aesthetic of the steel provided a striking contrast to the advanced technology within and referenced Nelson's maritime legacy.
The Farrapona Geological Viewpoint in Spain, designed by Puerto & Sánchez Arquitectos, utilized weathering steel for its extreme resilience against harsh climatic conditions. Located in a high mountain pass with significant temperature fluctuations, the material's toughness was essential. The viewpoint was prefabricated in nine sections and assembled on-site, demonstrating the material's adaptability to complex construction logistics.
Faulkner Architects' "Red Rock" in the USA showcases weathering steel as a durable and aesthetically appropriate material for challenging desert environments. This large concrete house near Las Vegas features a weathering steel cantilever that withstands desert conditions and visually references the geology of the Las Vegas Valley and Red Rock Canyon. The material's inherent characteristics allowed the structure to integrate seamlessly with its rugged surroundings.
Finally, the Sawmill Treehouse in Australia, designed by Robbie Walker, is a smaller residential project that effectively uses weathering steel. This cabin on stilts, situated on a steep, densely forested site in Victoria, employs slatted weathering steel to protect against summer heat and conceal utilities, achieving a clean, sculptural appearance. This project highlights weathering steel's versatility in smaller-scale, environmentally conscious designs.
The numerous projects from 2025 demonstrate weathering steel's multifaceted appeal in contemporary architecture. Its durability, low maintenance, and ability to develop a unique patina make it suitable for diverse applications, from large-scale public installations to intimate residential spaces. Architects continue to value its aesthetic qualities and structural integrity, ensuring its enduring presence in innovative design across various global contexts.
