How to get rid of the skimcoated thresh hold?

Hi
I have just pulled up my carpet in the lounge dinning room, and would love to put hardwood floors or laminate down. The problem is that since the kitchen has proper flooring and is quite a bit higher than the level of the lounge dinning room, to compensate there is kind of a small concrete ramp between the two rooms, which obviously creates a problem with both hard wood and laminate. How hard would it be to remove this? Is there any other way to deal with this?
thanks

Yeah, I'd advise removing it. how you proceed is going to depend on your specifics. what kind of subfloor do you have?
how high does the ramp go (ie, what's the different is heights from one floor to the other)?

The easiest way is with a sledge hammer, and the most precise is with a large grinder (also the dustiest!), but generally, I'll use a brick chisel and a 3lb hand sledge to break it up, since most times its a skim on top of the concrete foundation (around here, wood subfloors are uncommon on the first floor). If it is truly part of the foundation (unlikely, but possible), you'll have no choice but to grind it down.

If you can give me any relevant details, I could be more specific.
