Analysing Where The Current Boundaries Acually Are In Myself

Ive discovered that the boundaries are in the wrong place! So my defensive boundaries have been moved, shifted into place to block me from going to my wants and needs, while there is complete absence of boundary stone walls where defensive boundaries are required. So Ive got some renovating to do. I gotta knock down some walls and build up some stone walls elsewhere such as for defence.
I dont exactly know HOW to implement these renovations but at least as of now Ive figured out the core problem.
