Just completed a new house. We downsized and moved from a large 5,000 sf traditional but updated colonial with defined spaces (LR, DR, 2-story FR, etc.) to a 2800 sq basic house but with water views out the windows (can't see in these pics). Our main floor is now essentially one open space - long living/kitchen area which would typically have the DR table in the middle which I don't like, so we have the dining space off the end of the kitchen leaving us with a big open "ball room" in between.
Original plans called for a second island with columns in between with a wine bar, etc. but were afraid it would hamper the water view and we didn't have a good architect to help...now I think we should still do something like that (although we ended up doing another built-in for the wine/coffee bar in the dining alcove). I need help - I hate this open concept - it's not at all warm and inviting or comfortable.
