I think those are great ideas as that's what I was also thinking with what I'd change and do with the plans if we were building that plan. I'm not a fan of the only powder room entrance being in the mudroom, l prefer a more formal power room with the access to it in the common areas. So I like your idea of placing it in the butler's pantry area. Now if a plan is large enough to have two powder rooms such a private one also off the mudroom area I like that too. So the family can come in, wash up..... as they come in the door. Love the locker idea and am adding them in our new build as well. I really like what you have come up with. Good luck :)

A scale drawing would be helpful. Include all the features like Windows, doors, plumbing. This can be a hand drawing on graph paper. Take a picture of it and post it.

Can we see a floor plan with dimensions? No windows, right? Just that one door we can see? Could a stack-up laundry set fit into that space where the shelves are? What functions does the space need to provide? - Laundry - Shoe storage - What else?

This space definitely plays a lot of roles, and when a space is functioning as a laundry room, storage room, mudroom and entry, it’s a perfect opportunity for custom cabinetry to solve your design challenges. If this were my project, I’d start by removing the drying rack and adding closed storage for coats, shoes and backpacks, like in this project: And then add ceiling height cabinetry around the sink, washer/dryer and refrigerator. If you’re doing a full makeover, I would consider stacking your washer and dryer and adding custom cabinetry around it to make your vertical space more usable. As you can see in this stacked washer/dryer, I added doors to the cabinetry to hide the appliances when they are not in use. Finally, if you really want to give the space a clean, cohesive look, you could add a panel ready fridge to the space and use the same cabinet style to cover the fridge. Your space wears many hats, but with thoughtful design and custom cabinetry, you can hide your fridge, washer/dryer and mudroom.
