Estimating the Stairs Position

Measure the height of the stairs, we will work on the basis that all treads are ten inches wide and seven inches apart, (Ratio of 7:10). With these figures, divide the height of the stairs (in inches) by seven. The number you receive, is the amount of treads you will require, multiply this number by ten, and you have an estimate of your total stairs distance. For an example let’s say, if the stairs had a rise of seventy: 70 inches divided by 7 = 10, 10 x 10 inches = 100 inches.

Preparing the Ground

Ensure that the ground where the stairs will be situated is level, (you can lay gravel underneath if you have a problem with drainage)

Building the Steps

Pour your foundation to the designated area. You may also add a kicker plate, however this is optional (A kicker plate is a board attached to the foundation with bolts or concrete nails; the bottom of the stairs can be attached to it). Now to create your stringers, begin by marking the previously calculated dimensions of the step onto the short arm of a framing square; then place the framing square to the board with this mark on the outside edge of the board. Firmly hold the square into place and slide it up and down until the width on the long arm of the square is on edge of board. Outline around the edge of the framing square this will create a shape similar to a v, continue to do this until you have a zigzag shape from the continuous v shapes. Cut along the outline you have made using a circular saw/handsaw. Once you have your first stringer, you will begin crafting your second one by using the very same process while maintaining the same alignment. After you have both of your stringers, attach the top to an exposed joint with bolts, and attach the bottom of the stringer to your kicker plate using angle irons. Once completed, cut your risers and treads to the desired width of your stairway, leaving around a maximum of an inch overhang on each side. Then screw or nail your risers into place, add your treads, and fasten the bottom edges of the risers to the backs of the treads.
