Step 3: Location, balcony
Position the stair, choose opening shape or platform
Place the stair on your plan. It can be located at the edge of the balcony or with access through an opening in the balcony floor. Depending on the specific stair diameter and height, an opening in the balcony might be required for headroom clearance.
If your plan permits, place the spiral stair at different positions or add a platform extension. Use the other direction-of-turn cutout diagram for different tread placement. Try a different diameter stair for more possibilities.
If there is a balcony floor opening, decide what shape you want it to be—circular, rectangular, or something else.
The examples shown here are only a few of the many different spiral stair locations and openings that are possible. You should explore the possibilities with your contractor, who knows the details of your home and local building codes, and will be responsible for the installation.
