You need a different type of wm or dw for mounting on top of each other. You cannot do that with a regular machine. Both of the machines produce a lot of vibration. Please enquire with the manufacturer before deciding to do that. My opinion is not to have a wash basin in the dining room. Can you do something like a powder room near the dining area?

Suggestion: Never put the gas stove below the window and chimney against the window. It is ineffective as the air blown out is likely to come back in. At the least, it can be on the right or left side of the window with the chimney on the wall. Or the best place is on a slab on the left wall.
