There are quite a few companies supply log cabins in Ireland.
Considering that many settlers of the USA originated from Ireland, and that many of the original buildings used int he USA where log cabins, there is an obvious link between the buildings.
However there are not that many log cabins in Ireland. The reasons aren't clear, but I guess relatively cheap construction costs of concrete buildings meant most people opted for those. But Ireland, like Britain, is a cold place and log cabins and other wooden buildings offer warmth in not only their feel, but in their heat retention properties.
People are modelling their land and buildings more and more these days, and log cabins and becoming popular as extra buildings within peoples grounds.
If you're after a log cabin give Log Cabins Eire a look.
