The monumental steel staircase at the Vista Residence is the focus of a feature on Curbed. Assembled from 5/8” thick plate steel with white oak treads, the staircase took eight months to fabricate, assemble, and paint. During construction, a large opening was left in the roof structure so that the shop-fabricated sections could be lowered into place. The pieces were then bolted and welded together on site, and integrated into the main steel structure of the house. The stair is made up of over 200 individual pieces of steel joined by over 160 concealed bolts in addition to welds. The largest single piece of steel is 17 feet long and 10 feet tall.
