For this design...
Consider of the cost of this project in total (especially when you move the plumbing) i didn't do too much changes for the layout.
I put a minibar in right next to living room which you can use as an eating table and a storage at the same time.i choose to close the window on the right side, and put a cabinet for additional storage. For additional light, i put hidden light in the minibar area.
For the brick area, i just put open shelves there, so you can use it as a storage too.
For the corner side, of the back kitchen counter, i change it into open shelves again and for the other side, it will be closed cabinet.
In this design, i try to balance the portion of closed cabinet and open shelves, so it wouldn't look to close or too busy of the closed cabinet.
Hope you like my design :)
