If you do it beforehand it will be rather cold and drafty I suspect !
They would not believe this was the "original condition" of the house.
That trick might work with other things around the house however.
If you take the door off after it has been inspected, nobody will
know. Lots of people do this. Put them back on when its time to sell.
Heating bills will be high in winter though.

They'll probably be open a lot of the time in the summer anyway, so if
they're in the way of furniture, etc., you could take them off, and
put them back on in winter. My only concern would be to make sure that
the outside entrance to the conservatory was warm.

I'd leave the issue of whether to take the doors off until it was
built, done and dusted, though. As someone else has remarked, if it's
built with no doors, it won't meet the definition of a conservatory,
and is unlikely to meet regs for an extension.
