Seriously, though. It's going in an attic? Has anyone owned an attic for 100 years? Maybe I'm just American, but after 60 years or so, houses tend to get remodeled and/or demolished.
Seriously, we have cowsheds older than America 
The pier I walked on this afternoon was built in 1867, it looks pretty much the same as when it was built. And the pub I visited after has been a pub since late 1700's, it was however remodelled then as it was formally a place where cider was made. Not everything is pulled down every 60 years. So I reckon, a European loft has a good chance of surviving another 100 years (we gotta keep our chickens somewhere!)
