Plan Design

I have scoured the web trying to find that perfect plan that I have in my head. Needless to say I have not found that "perfect stock plan". I've come close, but it's not a log home plan. It's a conventional stick built plan.
There is a lot I have to consider in my plan. The most obvious is, it's a log home! Almost every aspect of the build will be different. From the shier weight on the foundation to the complexity of the roof system. The wiring, plumbing, and a/c ducts do not have hollow walls to be hidden in. I also have to consider the length of the logs I have to work with. Which will determine the max. size I can build.
The plan that I found is offered by Home Plans.com. There will be a lot of minor changes made to 1st floor such as window and door placements etc. The 2nd floor will be greatly altered with a full length shed dormer on the back side of the house and a master bath. The exterior will have a wrap-a-round porch.
Most Architects are not knowledgeable in log construction, therefore I will have to use someone that is. There are several such designers in Canada that are not affiliated with a log home company.
Dirkson Design Services Inc. and RCM CAD Design Drafting Ltd are a couple that I came across in my research that I really like. I have not contacted either company as of yet, but I hope to sometime in August.
