If the house is in framing and they have just completed rough plumbing than now is the time to have that moved. It will cost way less to adjust the plumbing and get a functional layout then to "make it work" and end up with a space that does meet your needs.

Because then you would likely tear it all out in a couple years to get it done right.

Build a pull-out ironing board into a ceiling-height cabinet next to the washer. In the same cabinet plan storage for laundry soap, dryer sheets, your iron, etc.

Next to the dryer extend the counter all the way to the wall. Use the space beneath for a pull-out for a garbage can and a basket to toss stuff that needs to be dry cleaned or hand washed. You could install low drawers right under the counter, handy for tossing stuff found in pockets, basic tools, mismatched socks...Above the counter you could do closed storage if needed, or an open shelf to store laundry baskets.

On the wall by the entrance door install a retractable clothes drying rack or two, depending on the space available. They are amazing. I have a heavy duty metal one and I found jumbo plastic clothespins that work with it, so I can hang a full load on it and it only takes up a few square feet when extended, almost nothing at all when pushed in.

Plan for a full size utility sink with a cupboard base, goose neck pulldown faucet, and a foot or two of counter on each side. (Remeber to leave enough room between the left side of the sink counter and the garbage cab for the drawer to pull out. Or just skip the pullout and have it open underneath if that doesn't bother you.) The first time you have to wash a big bucket or soak a desperately stained piece of clothing you'll be glad for the extra volume. Again, closed or open storage above the sink.
