I admit to not knowing the process, so I could be talking rubbish, but are houses not 'signed off' by an inspector of some description? If yes, yet again, this must have been an inspector that is overdue for their eye test. Even little things like the white plastic cover/shroud in the last pic on page 1. The bottom part not screwed to the wall at all and not properly reaching the upper part it's evidently supposed to connect to.
I'd be interested to know how houses built today compare to those built during the 1930's - 1980's, including council houses. For example, in each decade, I wonder what the average no. of snags was for each 100 houses built. I wonder if we'd see a line trending upwards from the 1930's to now? Or, in reality, has the UK always thrown its houses up? I can't see how. I was brought up in a 1960's council house that my gran had from new. They were decent houses. I then lived in a house built by Betts Homes in the 1980's, again it was decent enough although not the same build quality as the 1960's council house. Then lived in a 1930's built ex council house, it was totally solid (brick walls throughout) with great sound-proofing etc. I now live in a 1980's built timber frame house, it's decent enough although being a timber built house with paper thin walls, the sound-proofing isn't great.
Surely things should have been getting better over the years in terms of overall quality, not worse. I suppose it's like everything these days, everything built to a budget, cheapest materials used where possible, cheap labour etc.
