Is that a log cabin?

Currently we (my friends and me) are thinking about building something like that (log cabins) both to live it in and to rent it out for others too.

I am thinking about a caravan too, but they say that building a log cabin is much cheaper (only a few hundred Euros) than a caravan (which is at least around €2500 Euros) on Tenerife. Some wood raw material is already available.

We will see, but both are much better than continue living in a tent or in a cave. Currently I still live in a tent, but soon (in the near future, probably in a few months, or even sooner) I will have a proper accommodation again.
