To start with, there was one concrete step in front of our porch. The porch was 16 inch high and the step was 7 inches high. That meant that there was a 9 inch step from the step to the porch. Uneven, and of course, difficult for some people, especially of the older variety. I had cut a couple of one inch boards and put them under each end of the step which made two 8 inch steps, but that is stretching it for normal steps which are between 6.5 and 7 inches.
When I moved the step away, I found that a toad had made a nice home under it.
I cut out stringers and risers, and just laid them out to see how they fit.
Here's the finished product. Two 6.3 steps and one 6.3 step to the porch. So, now three small steps to get to the porch. Easy for young and old alike.
