Thanks Colin!
It is good to know your inspector thought vent holes were a good idea.
I asked this general question on our builders group last year. I was finally getting around to actually
making the holes and wanted some last opinions. The vent holes are now done so it is correct now!

The insides are coated with Rhodius Varnish - still trying to find out why Rhodius is the 'traditional' varnish for the job. It has been suggested that it is resistant to mould etc.
