This a great question…..

The mark of a unique and one-of-a-kind structure is the lack of repetitive elements found in other common homes; for instance your observation of log sizing.

Logs or timbered elements ideally would be selected based upon a number of variables including: structural capacity, esthetic or styling & expression, personal preference, site specificity and budget.

Whenever possible…hire a passionate & motivated Architect to help sort out these choices; you will be amazed with the end result.

To answer your question directly…logs of this type are generally available throughout the west; check online from Wyoming to British Columbia and everywhere in between. Compile a list of available species, lengths and diameter, character, price and approximate cost to drop ship to your destination.

The end result is definitely worth your while…

Hi Dan, That (above) being said, how do they mange to top the logs uniformly so that the roof lays perfectly flat. Do you have any advice as to this construction process?
P.S. Love this ranch house in the timber country of Montana. Makes me want to move... but my wife would kill me. :o)

The lack of uniformity achieved with natural logs adds a good deal of charm to this room. Thanks for sharing.
