Accuracy ; what’s that ?
I walked my build perimeter out - said “ that’ll do “ - “ near enough “ .
I then added 0.5m width to the build . I then went 0.5m higher than the plans .
Enforcement officer was called by neighbors regarding height . As officer knew nothing about the build I told him I had added ufh and the insulation had increased the build height .
Problem solved .
Tape measures stretch in the heat as does my stride .
