Open plan is this thing people who never had teenagers made up. It looks sweet. The reality is awful, AWFUL.
This. When my Grandfather passed away, my Grandparent's house got sold to a renovator who flipped it for profit, but not before renovating it to an open plan. This was a house originally built in the 60's. We saw some pictures of the renovations and while it looked elegant, it didn't look as practical.
We visited two house lottery homes this fall, and both used similar concepts. The big ticket home that most normally go for was horrible with some very questionable design decisions, including a master bathroom exiting off the kitchen; to exit the bathroom you had to walk across the doorway overlooking the kitchen to get to the master bedroom. It lacked a lot of privacy.
The second house was much better, less expensive a ticket and had more of an effort for giving much needed privacy. But the new trend both houses had were the main entryway being located in the basement, which meant a trip up two flights of stairs to get to the living-room/kitchen and the rest of the house.
