Residential Spiral Kit Stair

Close collaboration with the architect and homeowner drove the development of this custom kit-of-parts spiral stair connecting their patio to the second-floor deck.

Finding an affordable solution to the design vision was a key driver in the development of the stair parts. The primary elements are made out of painted aluminum; the treads are folded aluminum plate and handrails are short segments 5-axis machined out of aluminum blocks. Railing infill and cross bracing are our standard stainless-steel hardware.
