One of my kids finished his basement in a new house. To say it was successful is an under- statement - it is beautiful. Some of the things he did: Created a "foyer" at the base of the stairs with doors into a mechanical room, shop, cedar walk-in closet, bathroom, play room, and the main room. The foyer and main room are carpeted using "Comfort Base" under the carpet. Comfort Base is specifically used over concrete - I recommend it. Used metal studs and framing. Easy to use. If you have a sump I would suggest installing a water backup system. We have a high water table in this area; I pump water about every 10 minutes so a power outage can do severe damage. For me the water system is superior to the battery system assuming you have city water. Zollner makes such a pump. To cover the supporting beams he used the fluted aluminum posts normally used on porches. Looks great. At the end of the main room he built a wall about 2 feet out which allows for electronics and a 52" recessed TV. The walls and ceilings are all drywall with a "pull down" finish which avoids the mess of sanding. Good luck. Be interested in your progress.
