No matter the size, unless we are talking dog house, it takes a Loooong time! I did this five years ago-1,100 square feet and would never mess with cord wood again. Extremely labor intensive, heavy, sloppy, miserable process. They LOOK nice, but there are other approaches to building that do not destroy your back and knees and move along quicker.
I had plenty of dried wood cut to length and ready to go and had planned as much as I thought necessary. Never again. If you have logs available I would seriously suggest a more traditional log home. Daunting at first glance but flies up compared to cordwood. Not trying to rain on your parade but just a voice from someone who has been there and done that. Good luck to you no matter which route you take.
