I have a small store(1000sft.) in a strip mall in Miami and I want to expand into the space next to me. to do this I will need to remove about 10 ft. of the wall (cbs block)that seperates the stores. My question is are the walls that separate stores in this type of mall load bearing, or is it post and beam with the blocks filling in the space between the post? If I remove a celling panel I can see a beam that runs from the front to the rear of the store.
