This is my floor plan, by the way. You can see that my laundry room is a closet, and just so you know, I do know the doors need to be vented!

Your inspriration photo's have no closet doors and these wm and dryer can vent on top ( minimal, IMO ) or at both sides. If you don't follow the Samsung installation codes and your dryer may cause a fire, you insurance may not pay you

I would recommend you post this on the appliance forum for possibly a more technical answer. There are appliance experts over there:

This is a very good question though.

Lots of people do stupid things that don’t comply with design best practices. Like a 400 lb on top of a laundry set that needs to be pulled out and cleaned regularly. Or an incorrecyly sized standpipe subject yonivethlow because they didn’t want it to show above the washing machine. Or other very silly form over function decisions.

drain standpipe too short and/or too small diameter and may therefore overflow when washer pumps out, some pump out very high volume quickly.

In other news, I looked up the wrong specs. By one letter. We actually have an electric dryer. I am all smiles.

That's awesome.
