I've been looking through the old posts and thanks to your resourcefulness, I've been building a Stevenson Screen based on Flying Eye's in this thread:-

I have questions about Stevenson Screen roofs and floor.
Should the floor be ventilated in any way, made of slats or have holes in it? It is currently solid and up tight to the lower edge of the vents
Should the inner roof be ventilated, possibly have holes in it or any gaps say around the edges or even raised slightly? Again it is currently solid and sat on top of the upper edges of the vents.
Also how much larger should the upper roof be? The roof is about 9" square, so was thinking of making it 12" square which would give about 1" extra all round.
So far this has cost less than £20 for the vents and PVC angle, the wood for the roofs and floor I was given

Thanks in advance!
