Sounds great.
My kitchen is newly renovated... but I still like the dining room. Especially on holidays and special occasions. I eat in there too, it has a great view out the main window into the city park-across the street.
I have a dining room. It only has 3 walls and when we have lots of company we can turn the table & expand into adjacent space.
If you lose too many walls there is nowhere for pictures and the space becomes monotonous. It may be that the definition of open space is broader than people realize. Other commenters have borrowed from the Wiki article on the subject and the following is an additional part of that entry.
Frank Lloyd Wright was one of the early advocates for open plan design in houses,expanding on the ideas of Charles and Henry Greene and shingle style architecture. Wright’s designs were based on a centralized kitchen which opened to other public spaces of the home where the housewife would be “more hostess ‘officio’, operating in gracious relation to her home, instead of being a kitchen mechanic behind closed doors.”
