The template structures available using the Staircases form consist of three types of staircase: Staircase Type 1 (one flight of steps per story), Staircase Type 2 (two flights of steps per story) or Spiral Staircase.
Choose the type of staircase by clicking on it in the Staircase Type drop-down list in the upper left corner of the form. A drawing of the selected staircase type will be shown in the small display box.
Staircase Type 1 Dimensions This type of staircase consists of one flight of steps per story.
