The floor deck is framed using an engineered 14" TJI joist with 3/4" Advantec. I have used other products over the years like 3/4" osb with a waterproofing sealer or a competing product to Advantec but I haven't found one yet that performs like Advantec. I feel similar about using a TJI floor system.
We started to errect the antique log structure. The structure was taken down, cleaned, fumed for bugs, labled and shipped to our site by a company out of West Virginia called Antique Cabins and Barns, http://www.antiquecabinsandbarns.com/
The log cabin is finished and looks great. Some of the timbers are as thick as 22". No major problems getting the structure up except the top cord is a little bowed and out of level.
We started the stick framing around the log structure. To the left is the kitchen and the right is the connector wing for the bedroom wing. Things are moving along.
Starting the roof framing using 2x12 rafters so that we can insulate according to the codes in our area. The large clear story will allow a lot of light to fill the living room and a bump out window will provide seating for the loft window.
