Hi there, were planning to renovate our house. And of them is the ground floor. We need to change as well the stairs' steps. I am confused about the number of steps.. Ours is straight stairs no landing or platform.. Now my question here... Is the second floor itself is included on the number of steps? If its not included we have a total of 18 steps. If we will raise the ground floor one steps will be deducted so a total of 17 steps. Thanks
