The Kitchn:

In the past decade or so, life at home has become increasingly informal (Netflix and Trader Joe’s freezer meals, anyone?). Not surprisingly, our houses have grown to reflect that, too. A key indicator? The demise of formal living and dining rooms in favor of open concept living, where rooms flow into each other to maximize entertaining opportunities and casual togetherness. […]
While it may sound like nirvana for some, it often is a tricky layout to live with, in practice. To put it lightly: The walls were there for a reason!

They boil it down to three points: noise, needing to clean more with no place to hide clutter, and having to decorate to maintain separate spaces. I’m not a fan of open floorpans in general, but one of the big reasons for me would be the noise. I’m someone who has to have some quiet. Plus, I just like having separate spaces where I can step away and be alone for a while to catch up on news stories or write something.

Side note: Is eating Trader Joe’s freezer meals really, like, a thing?
