The machines should not be enclosed during operation. Dryers particulary need unrestricted airflow ... unless perhaps it's a non-vented condenser dryer.

You don't want those closed while they're running - they need air circulation, so they don't overheat.

Even if ventilation was not an issue-which it is as noted above-there are so many gaps in cabinetry that the sounds will still be well heard. It is like soundproofing your home against traffic noise-you have to seal as many gaps and crevices as possible.

You must follow the venting instructions for the appliances. You can't just shove them into closed cabinets like those pictured and operate them. One wonders whether such instructions were followed when these cabinets were designed.

Your ideas will ruin the kitchen and the machines.

Honestly do the laundry when you don't have guests. I agree just becuase you see it ina picture does not make it right.

I'm curious as to why you'd want to open a mudroom to a kitchen in the first place. Most people want that mess closed off.

^^ This.

To me, it makes perfect sense, and the door between my mud room and the kitchen is always open. Making my kitchen feel smaller with a closed door isn't offset by any benefit of "closing off" the mess of the mudroom - it's not as if I can pretend it doesn't exist if I can't see it. The kitchen is the perfect connection zone between different parts of the house, in my opinion, because everything happens there (good and bad, messy and neat). YMMV.

I have had a washer and dryer behind doors like that- they obscure very little of the noise. The doors are nice to hide the machines when not in use...

Just because it was designed, built, and looks nice does not mean it is a good idea. Cabinet doors would have to remain open in order for the washer door to be open a bit, after use, for mold prevention. If our house had cabinet doors in front of the washer/dryer, they would never be closed. Good air flow is important, as already mentioned above. A really quiet washer might be the better investment. Our Miele was extremely quiet; I had no idea how quiet it was until I replaced it with a Speed Queen. ;-)
