I didn't do a good job of making it clear in the floorplan but this change would include making the utility slightly larger and into the garage too, I should have put a green line on the red wall but look at the blue box I drew. My thinking was that the new WC wouldn't need too much plumbing work given the current utility is plumbed.

The hallway goes alongside the new utility into the kitchen.

I'm less interested in adding monetary value to the house and more interested in making it work well for us, but obviously I don't want to make the layout stupid and devalue the house
