Smart Space builds stair cases to fit your specific application and to meet the most stringent code. The picture shows a U-shaped or Switchback staircase with a self supported top landing. This particular design was chosen to fit a space requirement. The tread and railing was utilized to meet the local code. Smart Space builds staircases and landings to meet OSHA, BOCA, IBC, and UBC codes. U-Shaped or Switch back stairs are a good option when the deck height exceeds 12′.
