The main problem is the dampness and humidity of the greenhouse rotting the
wood as the condensation always drips down towards the ground rotting the
wood from the bottom. Also a problem where any sloping roof meets wood
inside the house.
Yes rotting is a big concern. The best I can do is give the wood a couple of layers treatment. I am thinking of coating the base in tar (don't know where I got that idea but sounds like a good one). Not sure what else I can do.

Are you saying where sloping roof meets wood is prone to rotting? I was thinking maybe it would be a good idea to have rubber spacers at intervals so the poly never actually touches the wood.

I can't see where youu intend to have a door,
What are the ground measurements, I have no idea what 3477 0677 is.
What is the back wall? part of the house or what.
3477 0677 is 3.48 meters. The base is 1m (left) x 3.2m (back) x 1.5 (right) x 3.48m (front). The space narrows as you move right to left.

I had difficulty getting across my idea for the door but what I had in mind was for poly sheet A to be on hinges and open like a growbox.

The back wall is the garden fence, there will be a small gap between the greenhouse and the fence. The back will be poly too as I don't want any wood exposed to the elements. The fence is 1.5m which is why I made the height 1.6m, didn't want to upset my neighbour but I will speak to her. Maybe a traditional pitched roof would be better.

I will take your comments onboard re the height and roof and do another drawing, I am curious why you would have the rook in one piece?
