Now that the finished basement project is just about, well, finished , I'm turning my attention to other parts of the house. We have a two bedroom, one bathroom ranch which we would like to turn into a three bedroom, two bathroom ranch. The plan would be to accomplish this by turning one bedroom into a bathroom (its right next to the current bathroom which will make plumbing easy) and simply putting in two bedrooms on the second floor which will involve tearing part of the roof off, putting in a staircase, etc... I have a pretty good idea of what I want to build, so estimating the materials is not that hard, but the labor and cost of disposal of the old roof and other demolition debris, and other costs are not so easy to determine. Can anyone give me a good per square foot price for a job like this in New Jersey? I'm just trying to ballpark what our goal should be as far as saving for it.
