I have 2 linen closet kits that were made by Mills Pride. They are complete minus the front doors. The doors in my kitchen cabinets were damaged so we purchased another kit and used the doors in the kitchen pantry. The closet kits have been stored since that time.
They are:
15" Wide
15" Deep
83" Tall
These would make a great started if you needed a cabinet and wanted to make or have doors. You could also make something different out of the pieces or you could modify the size.
