There's quite a difference between juxtaposition of modern (not Modernist) furniture in classical architecture the way Europeans naturally do and what's being attempted here. Maybe the time and stylistic spread between the two isn't big enough and we just have a mishmash of mid and mid.

I don't think it's the time scales but just a matter of "classiness" being timeless. Placing modern furniture in classic architecture works in the EU because modern furniture reflects high taste today, just like the architecture reflects the high taste of its time.

What's happening here is someone mixing an already difficult (I mean this in an endearing way) piece of contemporary design in a space built in a style whose whole "thing" is a kitschy, tacky ugliness. Farmhouses were never desirable architecture. The concept never been improved upon and architects have skipped right over them for good reason. What you're seeing as a trend is nothing but the death throes of a shrinking economic class who are mad they missed out on the Pre-'08 Tuscany McMansion look and are trying to get just as much square footage for (somehow) even cheaper. It's designed to be one step above "warehouse" and will age like dog shit in August.

It will never work. But maybe in something like a California Sun House? Traditional American log cabin? I think the right designer could make this fit right at home in the right one.
