As you know I have a little bit of experience of handrails but not of actually making a staircase. At our (hopefully) new place, the staircase is (a) very steep and (b) the treads are narrow. Am I right in saying that if I replace it with a staircase that is longer in the horizontal direction then that will (a) make the angle of the staircase less steep and (b) let me have wider treads ?
