Stairs without railing is to bring people and things from one height to another. You can design your stairs to be simple and utilitarian to be the center of a hall. However, there are some basic decisions you must make, including how long to do the stairs, how steep the steps to do, how deep to make the steps and on to the stairs open or closed. The best way to start is to design a standard staircase and then modify it to suit your needs and personal taste.
Develop an initial stairs without railing using standard measurements. Normal tread is 10 inches deep; the normal increase in each step is 7 inches high. Measure the height you need your stairs to reach the height and divide by 7 inches; round up any fraction. This will give you the number increases to your staircase will have.
Determine if you have enough space for the standard stairs without railing you just designed by calculating the horizontal distance from the top landing to the bottom landing. Adjust the tread depth or increase of stairs to fit the space you have available. You can adjust the increase of stages to between 5 and 8 inches. The rise of each step must be the same.
Decide whether you will use solid wood stairs and rip each step, typically 1-by-12-inch boards to fit or make treads from several smaller, cheaper, boards. Decide if you want to open or closed treads. Closed staircase has a thin extension card that covers the back of each step. Design width of the stairs to fit the space and the stairwell purpose.
