We never liked the galley closet in our Unity CB. We already have a closet near the bedroom, and the front closet just filled up with junk that spilled out. So we put in plywood cherry shelves. Now we can at least neatly organize it.
Simple project. We bought home depot cherry plywood (special ordered online), cut to size, and stained with Varathane traditional cherry and polyurethane.
For the front we applied cherry banding before staining. Easy to cut with scissors and apply with an iron. Then a little bit of sanding to remove any that sticks out.
Then simply attached using small angle brackets.
