The SA588 Weathering Steel Cabin was selected by AIA as the 2013 highest honor design award. This SA588Gr.A weatherproof steel hut has 4,800 square feet and is divided into two layers. The first layer is a long alloy high-strength weather-resistant steel plated carved wall, and the outer layer is layered bluestone mined from the surrounding. The construction of local materials is fully integrated into nature and contributes to sustainability.
