Questions on building a half-log hybrid home
Will be building a half log home within the next 12-24 months. In the design stages now (still). Thinking on Maine Cedar Log Homes as there homes are built in 8-16 ft wall sections at hoisted into place, being sealed and bolted together. Windows,flashing, Zip siding and logs are assembled in the factory and built using jigs. I have visited the factory and was pretty impressed with the quality of build and products. (ZIP siding, Anderson 400 series windows etc).
Would like to top off with a SIP roof on timber rafters 48" oc for roof.
Anyhow, my question is on costs for house width. I have a few different similar designs one 24' wide (built with 2X8 12ft joists) and another 28' wide built with 2X10 14ft joists. I am leaning towards the 12 footer design because I believe with will cost much less to build (based on a per sq ft cost) due mainly to the smaller floor joists and roof rafters required to span,(besides the obvious of less ZIP siding, studs and log siding....) which may be added back to the costs due to a longer design. (say a 24wX42L opposed to a 28wX36L, same sq footage)
Any thoughts on this?
