I am with Rick (fossil) at this point. You have a bunch on your plate. You know your going to have a stove. You want to reuse the current flue (probably lined). Your going to do as much of the work as you can, yourself. Good enough for now. Get your room built. The stove will be one of the easy jobs. To "Prebuild" might bite you in the rear-end.
Case in point. You build your hearth floor pad. Did you build it as ember protect (because you are going to use a Quad Isle Royal) or did you build it to an R value that the Englander 30 requires. Food for thought.
