About all you need to do is get a dishwasher made to take a panel ("integrated" models) which come, as these things so often do, with a surcharge, although in essence you're getting less for the money (they come with no front at all). The literature will tell you the exact dimensions of the panel you'll need, and it screws on very easily (I did it myself with a friend to help hold it). You can just pass on the dimensions to your cabinet company or carpenter. There are also a number of independent companies that make panels in a zillion styles and materials (Frigo, Heartland, etc).

I am impressed by how clean my SS Miele looks. I didn't clean it for many months after install. Then I was leaning down one day to pick up some thing from the floor and saw a water drip line. When I bent in front of the DW to wipe that drip with a wet microfiber on a sunny day, I was shocked to see more streaks and some gunky places. These could not be seen at standing height or sitting-at-barstool-height in regular light. The DW always looked clean. And, the spots were easy to wipe clean. My KA fridge is a whole different story. Ugh. I wish it were made with Miele's SS.

I agree with the Cooks Kitchen. We had a very similar problem. We had a paneled vaulted ceiling, painted white, in a bedroom. There was no insulation in the ceiling...just the wood paneling, then roof paper and then composite shingles. We never had a leak but we would get mold/mildew (it was grey in color) on the ceiling. This room was on the shady side (not sure if that made a difference) of our one story house, not near any bathrooms or laundry. This mold/mildew would build up over time. Every year I would wipe the ceiling with bleach (we had wood-looking linoleum so I didn’t have to worry about bleaching carpet ) . We finally put in a heater with the vents high up in the wall. This ventilation helped a bit but still had to bleach the ceiling every couple years. We are in the process of remodeling this side of the house. Hopefully the insulation will make the difference. In the meantime maybe try a dehumidifier or heater or some fans. Good luck.

Some people have luck painting all surfaces (walls and ceilings) with something like Kilz that seals the walls before painting. I would check with a wood floor specialist to see if you can use a sealer on the floor for now that would be easy to sand off when you're ready to refinish them in the future, if you can't to it now. Don't forget the doors and all the trim in the room. They will need to be sealed, too. You have to get all the smoke smell removed before you install carpeting or it will just absorb the odor, too. Laminate is non porous so shouldn't hold the smell - thorough washing should remove anything lingering on the top of it. Do not use an ozone producing device...they are hazardous to your health and to the earth...https://www.epa.gov/indoor-air-quality-iaq/ozone-generators-are-sold-air-cleaners Good luck. I can't offer you much hope...I bought a used truck 17 years ago. Didn't smell smoke in it until the thorough cleaning the dealer gave it wore off and I could smell smoke. After all this time and numerous detailings, when the truck sits in the hot sun, I can still get a whiff of old smoke :(
