Renovation: timber frame for a hidden door

[@willpea1445]

Paul, you have such exacting standards - so I'm delighted to see you will live with a 1 mm difference in the diagonal measurements of the door ...

I’ve learnt that doors are tricky. Yes 1mm is ok 🤣 But I have also realised that you really don’t have much room for error in measurements when making doors and door frames. Otherwise the door just won’t close.
