Unbuildable and can't tear down

I know you guys were interested in unbuildable buildings, well I made one. At first seemed to be going well then suddenly construction stopped. When I told them to tear it down, they took down parts of the building and then wouldn’t finish deconstruction.
Building design was base 13x13 corner 1 block removed, two free standing wall sections on each side, 1 slab pillar on the inside corner to connect walls. Slab as roof with 3x3 hole in middle, wall sections around hole, and slab edging on top of wall sections.
