Crawl space into finished room?

[timfytoo]

We have recently purchased a split level house in Columbus and we have a 7' "crawl space the size of our kitchen and dining room. The floor seems to be a gravel covered by plastic (we have a radon system installed.) We would consider having the space finished so we could use it as a playroom/guest room. Main problems being two large round duct tubing going through the center and the floor. Is it worth going through the trouble/expense to making this a usable room and not just box storage space? What problems may I run into? Any suggestions?

I see lot's of $ figures in this one...7' is quite a "crawl" space but you'll end up losing some of that for your slab/flooring since it's a gravel bed now unless you excavate. Not sure what the "Tubes" are unless it's HVAC. If your gifted enough to tackle it yourself it might be worthwhile but lot's of $'s for third party..
