Yep, still think about it daily. Makes me want to move house, genuinely. Looking on the brighter side, could have been worse and been structural/an extension/ had to balance the shit around a young family - just me to sort it out and deal with it
If it makes you feel any better I met someone who used resi, and a resi approved and recommended builder, and they fucked up so bad their house fell down.
IIRC poor Bobble had a lot of bad fortune from a criminal builder
