Framing of log structure

[Isso]

Hello,
A friend asked me if there are any fittings for framing a newly built log house. The idea is to frame c/c 400 with 45*45, install drywall, and tile (bathroom). Since the logs move, the framing must be floating. How should one proceed? Are there any special fittings with slots or something?

You should have what are called glidlister. I can't say offhand if there are ready-made ones, but in any case, it's a simple construction. My suggestion is to contact a carpenter, why not the one who built the house?! Where is the house built?
