I've found it interesting the wide variety of floors in basements, no matter the age of the building......the house I just moved from recently was built in 1912....but it had 9 foot ceilings and a nice (unfinished) basement....with a perfect smooth concrete floor.....just as good or better than any modern building I've been in...

But I know some people with a house from the 30's and it has the uneven rough cement floor (one room is dirt).........and the ceiling is about 5.5 feet.....guess it all depends on the cost of the house when it was built.
