I want to remove 2 8' walls, 90 degree angles to each other that separate my living room from the kitchen area. I would like to make them both stub walls for an eating counter. Am I better off removing the walls entirely and starting from scratch or removing just the upper portion and leaving the bottom portion for my eating counter. The ceiling is a painted smooth finish. How can I do this with as little damage to the ceiling as possible? Thanx for any help.
