Just an observation but It seems there are "log cabins" and mobile homes that can look like "log cabins" , i assume the latter may be easier to get planning for may be cheaper and quicker to install , Are almost certinley not as good as proper log cabin . BUT from a money making perspective may or may not be better .
It depends to some degree on who your clientel is likley to be my guess would be 80% or more of the public would not no the differnace, the luxury end might and may pay a premium for the real thing , but alot of the big hoiday park operators seem to be selling "log cabin accomdation" that is really double width mobile homes clad in wood .
We bought ours from a company that eventually became Nordic Log. I can't vouch for the company as we've not dealt with them since the change of name and owner but the product they are importing is very good. We were able to get RDPE funding to help with the build costs and payback was very quick.
This might be a good time to get into the UK holiday industry if you time it right - I just can't see the air travel / foreign holiday industry recovering to the level we have seen recently, but people still want holidays.
There is going to be a lot of pain and business failures until we get there though
