Hi Conor, I'll see if I can round up some pictures to post.. as for how old our cabin is the first room was built in 1980 and just one room we continued ,to build on as we had the time and could afford it. The last room was added in about 1995.
We haven't had to do much maintenance ,every few years we oil the outside logs. The big issue with logs is to keep them dry, we did have some issues where water got into the logs and caused some decay we were able to correct this problem in various ways by using cement patching or log inserts. The main thing Is to put a good roof on and be generous with the overhangs.
In 1980 I bought a 40-acre piece with a large amount of Popplar, what you might call Aspen, we went directly to the woods and built the cabin using the native trees and sand from a creek on the property for footings and chinking.. it's been a very enjoyable and economical way to keep a roof over our heads for nearly 40 years..
