Looking at the video, is it me or does the part of the block to the right of centre appear to fall over the fencing surrounding the site? And if my house had of been one of the ones opposite I think I would have been a bit worried.
I'm not so sure that they didn't plan it that way. Clearly they had previously removed much of the outer walls half way up where the black plastic is. If both walls had collapsed in the same direction then wouldn't all the rubble be 'fighting' for the same space? By letting the lh wall come out, the left central go in and the right central come out then that would give each wall somewhere to go. .....I think..I'm not a demolition expert. I do agree though that that right wall does come over the fence.
