Making more cabinet space under a bar counter

I was living in my parents' house during and after my divorce, trying to recover economically.  Their upstairs had a bar counter and a small bar sink.  When I was living alone, the kitchen space wasn't a problem because feeding one person there really wasn't hard with a microwave and other small appliances that I already had purchased for hotel cooking while visiting my boys.  But when my boys moved down I needed more space to store food since going out to eat when I didn't feel like cooking wasn't as feasible an option feeding three instead of one.  I made better use of the bar cabinets, and I'll show you how here.

Step 1 Planning

The cabinets under the bar counter were very deep- when I bought organizers to store dishes and things underneath them, they seemed to get lost, and the space was almost unusable for smaller items.  So I measured the cabinets, and planned for what would be on the under side and what would be stored on the front side.  I decided to make the front side (the new space) like pantry cabinets, so I measured things like cereal boxes since I figured that would be about the deepest box of food item I would be storing.  I checked to make sure that the items on the other side would still fit after subtracting the space for the boxes and the cabinets themselves, and success!  The project could move forward.  I decided to make the cabinet doors out of the same paneling that was already there so as to disturb the look of it as little as possible, so once I did some more measuring inside the existing cabinet to determine the maximum size the new shelves could be, I transferred those measurements to the front of the cabinet.
