Weather Proofing for long lasting

[iamterryclark]

Beautiful plans, thanks for designing them!

My question is, as this might sit outside do you have any advice on weather-proofing it or is this design ideally used for indoor / sheltered purposes?

Thanks in advance

My guess as hobby-woodworker and professional gardener:

It’s based on multi-layered wood so it’s not really for outside usage. You could make it a bit more bullet proof by adding some outdoor wood oil but it’ll not last longer than say about 2 years outside. If you wanna do it outside, you need to switch material for some high pressure glued wood and then carefully seal all cuts again and add varnish as a finish probably.
