I got mine from this company https://www.heartofenglandgroup.co.uk/log-cabins-photo-gallery I cannot fault the service, they are not the cheapest but the service was superb, really held my hands through the process, really recommended for no stress build.
Hints and tips, get someone that can give you a certificate for the electrics, make sure you can get enough amps out to the cabin from your house ring/Spur.
I would suggest going for decent thickness of logs for the walls, not the 22mm, it will help insulate it, as you will see from comments, i went for double bearers for the floor, purely as there is a lot of weight on the floor, and it can get very "springy", like a nightlub dance floor if not supported. I raised mine purely because the way my garden is, i am at the bottom of a hill, and the water tends to flood into my garden from all around, last thing i wanted was a soggy floor.
Thanks for this - I'll contact them for an idea of prices.
The electrics will be done by a qualified person, and I was thinking of having a new consumer unit in the garage, direct from the incoming supply specifically to service the cabin and some additional points in the garage, so capacity shouldn't be an issue.
Agree re. the logs - was thinking absolute minimum 44mm and maybe 58mm or thicker depending on price.
Good point re. the floor - double bearers sounds like a sensible precaution against having the floor move which would obviously ruin the experience of playing pins.
Yours looks really good - especially the lighting and bar bits!
One question has come up through further thinking about it - what do people do regarding temperature control - so heating in the winter and potential cooling in the hotter parts of summer? I did notice that one of the suppliers had a log burner option, but I'm not sure how practical this would be unless spending long periods of time in the cabin.
Any other tips from anyone really welcome. Thanks.
