I bought a new Wimpey house a couple of years ago and all the doors were fitted with what I can only describe as "pop off" hinges. A plate was screwed onto the jamb and the other half of the hinge which was screwed onto the door had a piece sticking out which went into a groove under the plate and was held in place by a "springy bit".
When you needed to remove the door you just lifted sprung part with a screwdriver and pushed the door out.
Currently replacing all the doors in my new (much older) house and price permitting would like to fit similar.
Does anyone know where they can be bought? I've looked in the usual sheds and the likes of srewfix with no joy (or I'm blind).
Cheers
