Timeline for building a log or timber home
This will depend on many factors, including your contractor, the weather, and material supplies.  Most homes take between 6 and 12 months to construct.
While the most unknown areas, like the foundation, can depend greatly on weather, once the basement, crawl space, or slab is in place, the job can usually progress throughout any season.  Once out of the foundation area of the build, the homes usually take 4-5 months to complete.
Obviously things like landscaping and log home stain have to be completed when the weather is cooperative, but most of the other areas aren’t weather dependent.
