So brick walls on all four sides?
In reality, I'm sure that the column would be braced. I wouldn't personally rely on it though unless I was very desperate. It takes a fair bit of strength and stiffness to brace a typical concrete column. Proving that the brick walls could do the job without crushing, shearing, or buckling could be difficult. Kinda depends how beefy those walls are I guess.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
