I don't think I would like the distraction of up to seven people talking to me whilst cooking, the food would turn take ages and turn out rubbish! My mum used to handle it without a problem though.
We have a massive L shaped open plan in our rental - 20 X 30 X 20, with a separate utility room.
I like that we have to do washing up straight away because I hate coming down to muck in the morning so it gets done straight away and the OH can't really get away with 'forgetting' when it's in his face.
I dislike that the vast number and sizes of windows in the room turns the whole area into a sauna for all of summer.
It's big enough for cooking smells not to hang around, even without using an extractor.
There's a separate utility room, so no WM noises.
We put the DW on just before bed.
I find it really useful to be able to easily get my OH's attention for heavy things whilst cooking as I am somewhat disabled.
I hate with a passion that the underfloor heating under sandstone floors takes five hours to heat up. Some of the zones have overlapping pipework too, so several foot across the room becomes unbearably hot (of course, underneath a sofa!).
It works for two of us with no kids. I can see how it would be a nightmare for folks who never get a quiet moment to themselves.
