Ah ok, that is fairly high. I believe in CPT you can only go up to 2.1m without building plans.
...
All walls in CoCT require plans regardless of the height as per the new bylaws***. 2.1m is the max height for any perimeter wall even with building plans. The height of wall is measured on the higher of the two sides. And if its near a street corner, then the height drops to 1m.
You also need to ensure that 40% of the wall is visually permeable.
