With all due respect, I agree with ypg. It really should be drawn to scale, using graph paper. The interior doors are only small catches compared to the front door, and if the dining area is about 3 meters wide, about 3.5 meters remain for the living room. The furniture in this form would not have nearly that much space. Such an open floor plan is a matter of taste, but at least a windbreak door is practical so that the whole house doesn’t get cold immediately in winter when someone enters. The staircase is not like that.... As a very rough sketch it’s okay, but nothing more.
