Removing cement floor

I just bought a house that had the garage converted into a bedroom and all they did with the floor is glue carpet on top of the cement floor. There are two problems with this room:
1st the floor is not level. It slopes a total of 4 from the back of the room to the front.
2nd the ceiling is very low. It is 84 in the back of the room and 80 at front.

I was hoping that I could rip out the floor and lower it by at least a half a foot and make it level. The house was built in 1941 so I am not sure how the footings for the garage is or how deep they go. Is it possible (and wise to lower the floor) or should I just level it out and just live with the short ceiling.

Any help would be great Thanks!

It's hard to say if it is possible without seeing how it was built. However, one thing springs to mind immediately. Since it used to be a garage, if you lower the floor, it will be below ground level. If the foundation is not waterproof, or if you have drainage issues, that floor could end up being a very deep puddle when it rains. See Michael Chang's numerous posts below.

I am not too woried about leaks being a problem because the house has a basement right next to it and the basement is dry. So I assume that the floor would be dry too.

Removing cement floor

When you pour a new slab use a vapor barrier under the slab. This probably is not under your existing slab, but it is a good thing for general moisiture control.

The Chang posts should not scare you because his is a unique situation that sounds like something that should not have been built in the back yard because of the site and drainage.

You are talking about a 12" drop, not several feet below grade in a low site with poor soil conditions.

Yes you can replace the garage floor , make sure you have a good compacted subgrade lay down a good moisture barrier which will also help with the concrete not setting to fast as water being soked up by sub grade also itll need to be atleast 4 inches thick , itll need wire mesh and have mesh chairs which hold the mesh up while the concrete is being placed , the mesh will do you no good laying flat on the ground , use a 4000 psi in 28 days 6 bag air entrained concrete mix , expansion joints where old concrete meets new concrete and control joints at least every 10 feet , i would apply a smooth finish and use a curing compound to help with the curing or atleast keep it covered with plastic a few days . these type of slabs are generally not for the beginner you have to place , straightedge , float , and catch the edges for starters its less headache to just hire a trusted contractor unless your strapped for cash ! ive seen many slabs that have gotton away from people that i have had to come and tear out and replace which cost the homeowner more money than if they would of had me do it from the begining !
