Abstract The paper presents emblematic modern architectural projects that use innovative steel structures. These projects often involve complex, unconventional geometries. Steel enables ambitious architectural forms without sacrificing performance or constructability. Case studies include an egg‐shaped office, advanced skylights, and intricate façades. The structural design is shown as an active part of the architectural concept. Steel's versatility, strength, and precision make it ideal for such challenges. Digital tools like parametric modelling and BIM supports collaboration and efficiency. Overall, the paper highlights steel as both structure and defining architectural identity, reviewing also the relationship between engineers and architects.
