We've had a quote to build a decked area against our log cabin, and it details digging in/concreting big posts (possibly 6x6" from memory) as you would gate posts.
However I was wondering is this really necessary? Our cabin itself sits on plinth foundations (https://swiftfoundations.co.uk/swift_plinth/) buried barely 6" and relies on spreading the load over greater surface area.
This is a whole building so could the same principle be applied to decking which will have very low loads? Or in fact, maybe this IS a common way? The ground is pretty stable on site.
I could buy some actual plinth things but given the low loads what I was actually considering was each post resting on something simple like a concrete paving slab, probably atop some pea gravel.
Has anyone done this here or seen it done?
