Architectural Designs - Is there a term for when you have your kitchen, dining room, and living room together?

Is there a term for when you have your kitchen, dining room, and living room together?

Like an "Interior Design Term" - or something - for when you have all of those rooms together, with no walls to divide them???

I think its called an open room!
Open floorplan or open concept
Open floorplan, rooms not including kitchen - great room, you could call it "first level".
Probably "open floor plan" unless it's an apartment, then "studio apartment". Hope I helped :)
