Again, just pointing out that the entrance on the right side of the room should have the same wall height as the rest of the room in this case, three tiles high). This is because they're sharing the same ceiling height, meaning that if the right wall were really only one tile high it'd be floating off the ground.

Also, you should make rooms that are connected to each other the same wall heights (so the lounge has 2 tile high walls, but this has 3 tile high walls. That would be quite odd if you walked into a house that had the kitchen ceiling much taller than the connected hallway, and then a much lower ceiling in the lounge room, with the bathroom having a taller ceiling than all the other rooms, especially if there's a top floor to the house).

Lastly, in future games you should probably focus on making rooms a bit smaller. You're obviously struggling to fill this room (with plants, a washing machine and a flower table just hanging around for no reason), so cutting down on the size of the room would really help with that.
