however, the OP's idea would leave a very oddly arranged greenhouse as
the door would be on the end originally - now the long side - which
would be a bit odd.


The door would still be on the 6ft side which is where it would be on
a 6x4 greenhouse anyway....as I said these greenhouses seem very
modular and designed so the manufacturer just adds 2ft middle sections
with the support rails being chopped off at the right length.
I only asked because there's a 6x8 maybe going cheap near me, Halls so
a good brand, and it would give me another option.
