Hey all, thanks for the comments, I'll try and answer some of your questions and comments.
First I tried to take some internal photos but it does not really come out well on my camera phone as its a bit dark due to the window masking and there is no sense of scale as its empty so you'll have to wait for that.
Mark A; the base colour is a clear basecoat, the final coat will be slightly pigmented - it needs to have a slight pigment to protect the cabin from UV. I cant leave it like this as it not waterproof yet. The final colour will be slightly darker, however I am not doing that today as its gonna rain tonight.
1pudding1; its impossible to give it an exact thermal rating as it varies from log to log. What I can say is this is north scandinavian pine slow grown in cold conditions so the grains are very narrow. This is important as it improves thermal efficiency drastically, some of the cheaper logs you may see in some cabins in garden centres are not made out of such good quality wood.
Nightglow; We looked at an attic conversion but we have a weird roof and there's not enough headroom up there.
cainer; yes I laid it on builders sand mixed 7:1 with cement for the reason that I had 3/4 of a tonne left over from the building materials and we intend to block pave it next year when we have the money saved, so its only sort of temporary.
The Brooder - Keops Interlock
www.logcabins.co.uk. It is custom made so not a model number. In fact we looked around the local cabin suppliers and it is much better quality than anything they could offer, plus they only offer standard sizes - here i got to spec the exact size, choose the rooms and the doors/windows etc and had it manufactured. Although the off the shelf cabin would have been cheaper, I would have had to put up with the prescribed size and by the time you add insulation options and double glazing etc the Keops custom made actually worked out marginally CHEAPER, plus they came and put it up for me.
Feek and Breeze, Difference between a log cabin and a shed. A shed is made froma frame with close boarded boards. This is an interlocked log system with double tounge and groove. The image below shows the interlock I also included a pound coin on the second image to give you scale of the log size.

yes a few of the tongues are slightly split on the ends, nothing to worry about so long as you work in the wood preserver and paint.
