Plot stuck - no asam

[Sapphire_xx]

Hi, Ive had a plot stuck as just scaffolds with no asams in my vault, how to i remove it? It was a while ago, i destroyed it before it was done building and before the asam appeared so its just stuck there looking stupid (haha). Thanks in advance!

Can you select it at all in workshop mode? Maybe pick it up and put it back down or store it?
