Full kitchen remodel.

An L shape kitchen with one side open to the living room —- would like to put in an island or peninsula

1. Can’t remove the wall partition as it has electrical
2. Should the peninsula be attached to the partition or opposite side. (The marked 12 foot opening is completely open to the living room)
3. Should I skip upper cabinets for a clean look on the sink/window wall —- the window is 6 feet wide!

Note: to the left of the partition is a hallway
