If there's one material Tom Kundig of Seattle firm Olson Kundig Architects is known for deploying in his projects, it's steel. Whether polished to a spectacular luster or left to weather with the elements, used as a structural support or applied as a refined accent, steel has the flexibility to be used in myriad ways. "Steel is just such a terrific material," Kundig says. "Virtually all of my projects have some sort of steel involved and hopefully, if I'm doing my job, I'm using it appropriately."
