Is there room to put a shallow basket-type storage on the back of the right-hand door, for little things like stain treatments, dryer sheets, swiffer sheets, spray cleaner bottles, maybe a roll of paper towels? Even if the cabinetry has to be a bit shallower? and on one of the doors, hooks/clamps for a broom, swiffer, dustpan, stepstool? (i have one of those little folding stepstools like this i keep in the seatback pocket of the car, they are that thin but very handy.)

Thank you, bpath, for the suggestions. I plan to place most of the items you mention in the narrow shelving on the right wall above and down to the counter. Your idea of a stool is something to consider. I planned to have an 8” gap on the left wall before the appliance enclosure. Could store there, but maybe a toekick drawer would work.

Add a fan to your drying rack.

Partim—do tell more!

We stayed at a home near Dublin a few years ago and they had a big drying rack with a small fan and heater under it. Dried clothes quickly with far less energy use than a dryer. Not sure what kind of drying rack you are going to put in but a fan, even a small clip-on fan nearby, will help things dry much more quickly.
