Second Floor Addition Costs in South Eastern PA
I've been trying to get a per sqft cost for a second floor addition (finished vs unfinished cost) for the Plymouth Meeting, PA area (about 20min north of Philly). From what I gather costs are quite variable based on region. I'm looking at putting up a second floor 625 sqft addition (possibly more, based on cost) which would include a large master bedroom with walk-in closet and master bathroom.
For the unfinished option, I would have the framing, roof, windows, and siding done by the outside contractor(s), everything else would be taken care of after the fact.
Feedback is very much appreciated.
