I’m looking for some advice for a co-worker. He has a log home that recently was expanded. The the floor level of the addition is not flush with the existing floor. The addition splits the house from front to back and the joint lies in the middle of the great room. The original floor (wood decking on floor joists laid on top of concrete piers) is about 3/4 inch lower at the back of the house and about 2 inches lower at the front of the house (approximately 25 ft. front to back). Any suggestions on how to minimze the differences in the two levels of floor? The rest of the construction has been completed so jacking up the old side is not an option. Thanks for any advice.

Here's all I can tell you.
On a job of an addition to an 1825 timberframe house we encountered the same situation sort of. There was a hump in the middle of the old place. We opened up 2/3's of the room as an extension to the kitchen, the last 1/3 was to be the laundry room.
We kept the addition right to about 3/4's of the highest spot. Then we planed out the joists (tapered sleepers) into the addition so the floor flattened-not being level in the transition, but at least no hump. The addition was 16' deep, the sleepers from 2' to 7' long.
In your situation, with the subfloor down in the addition and I assume fin. floor in the old section, you could still sleeper, but it won't be easy. If you plan on resheeting the whole shebang, it might be a better result. Bridging across that joint is a key part of it.
In these cases a straight edge sometimes is a more valuable tool than a level. Whoever put the addition on should have known the discrepancy and figured into the equation, how to deal with it. But that's easy for me to say sitting in this warm house in NW Oh. Best of luck.
A great place for Information, Comraderie, and a sucker punch.
