Hi, Americans call them Log Cabins... Probably whatever straight trees are available.These are awesome.
What timber (tree species) is used?
Any of the inside finished?
That would take some skill to cut the rounds into the logs for the mating one above.
A delightful hut or whatever you call them over there.
(We'd call an equivalent here a bush hut.)
Log cabin is more an Outside term (how Alaskans refer to the rest of the United States). It is a log cabin but, considering the location, it's more likely to be referred to as a dry cabin (note the lack of plumbing leads in the images), a cabin, or---with regular use---just a house or a place. See also dry cabin living.Americans call them log cabins.
I suspect that's probably white spruce (Picea mariana) but am less sure of the ID than I'd like. For the location and apparently local log harvest, Picea would likely be preferred for minimizing long term shrink and chinking gapping and slightly higher R value. Presumably Bristolero will be back eventually.What timber (tree species) is used?
Depends on what exactly you mean by finishing as well as use, history, and owner interest. Generally more finishing is associated with more use and time since construction. The logs expand and contract with the seasons so any interior work has to allow for that. Most commonly logs are fully sealed and left exposed on the inside.Any of the inside finished?
Not as much as you might think. Usually it's bring the next log up, lift it a bit, rip a mating surface with a chainsaw, potentially place gap filling insulation, lower the log, and repeat. It's preferred as it makes for a tighter, thicker, warmer wall but it's a lot of tedious work and means more logs. Good fits at the corners, purlin, ridge, windows, and doors take time too. Easy to lose more heat through the roof and floor if those aren't done well, though.That would take some skill to cut the rounds into the logs for the mating one above.
