I have a 1977 house with staircase with half landing and a cupboard under the stairs. Instead of having railing the wall from the cupboard is used instead. I want to remove the whole lot and replace with a wooden staircase with half landing and no cupboard has anyone done this? I am intending if its possible to get contractor to do the work its not a diy project. I know my limits and this is way past what I can do myself.
