Custom Steel Spiral Staircase

The bottom photo shows this staircase being assembled in our shop before it ever got to the jobsite, and the top shows it fully installed on the building. We fabricate everything in house which is worth showing because it's a big part of how we maintain quality control from start to finish.

A spiral staircase is one of the more complex fabrication jobs we take on. Every tread radiates off the center column at a consistent rise and rotation, the center post has to be perfectly plumb once it's set, and the whole structure has to land correctly at both the bottom and the top entry point. Any error in the layout compounds as you go up, so the shop work has to be precise before a single piece leaves the floor.

The ornamental detail on the railing at the base was a custom element the homeowner wanted to add a decorative touch to what is otherwise a very functional structure. It ties in with the character of the building and softens the transition from the staircase into the garden level. The finished installation is a good example of what we can deliver when fabrication and design work together from the beginning of a project.
