Here is the first attempt at a layout. When looking at the pictures above, this is on the blank wall. On the upper cabinets, I will make a corner transition to meet up with the current cabinets. The lowers will just meet at a right angle and I would put the sink at a 45 degree angle where the two bottom cabinets meet.
I think I came up with a good way to lock up the top shelf stuff. If you are familiar with a Lawyer bookcase, it has glass doors that flip up and push into the bookcase. I could do that here; normally closed but flip it up and hide the door when you have company. Having it closed would keep the UV light out also.
All lighting would be LED's as suggested.
Hopefully this will cultivate some discussion.
