I want to build a timber framed log store as an extension to a timber garden shed. Source of drawings?

I haven't surfed, but you might certainly find general sketches, photos etc., showing similar to what you seek, in just a keyword search of the WWW.





It may be more a challenge to find Prints, and methods, directing you from beginning to completion.





I assume you have access to this existing shed? If so, duplicate at least in part, the methods used in constructing it.





Want to build, is a great notion, but you may find issues, such as Codes that need to be followed, permitting, utility issues, etc.
