Is it difficult to build a greenhouse?

Not only make sure the base is square but also level or the glass will not fit square to the frames

 

I'll be watching intently Val as I will probably have to get a greenhouse myself for my growing epiphyllum collection as the subtle hints about them taking over the window sills have suddenley become much less subtle...

 

I put my first greenhouse up with the help of a friend....never again.
My subsequent greenhouses, I have paid someone with know how. It might have cost, but I didn't have the stress of it.

 

My number one rule when assembling/reassembling anything is this. Never fully tighten anything, until everything is in place.

 

val i am sure you will be fine, i put this one up on my own last autumn and it is still standing

i would agree that you have to make sure that the base is level and measure your diagonals to get your perfect corners, and l will await your pictures and your completed greenhouse will be amazing i am sure
