SU 8115 is a semi-circular cut in room I7, the exact function of which cannot be ascertained with certainty. It was possibly made for a post hole after abandonment of the structure, though it seems rather large for this. It may relate to the other cut features in the structure, as well as those in the same room I7 (most of the latter have not yet been fully explored).
Circular cut in room I7 and irregular cut in SE corner of room I7.
