I am in the process of building a 2 story addition which includes a 24 x 25 2 car garage. I have tackled the heating issue by adding radiant floor heating under the concrete. Other then adding extra outlets, cable TV, a sink, what else have I forgot? I have wireless telephone and internet connections which shouldn't be a problem. The ceiling height is 9 foot. A lift is a thought, but I have found my "wrenching" time to be less and less rewarding and I don't desire the obstruction when not in use. Suggestions welcome!
