Two other things I forgot... 1) DO NOT USE hardwoods, they apparently absorb water badly. 2) Plumbing secret: if at all possible, run water and drain lines (underground) to a central hub or area and build all your plumbing needs around this (back the kitchen onto the bathroom and laundry room) this saves a ton of money, as the opposed to having the kitchen in one corner, the bathroom in another which requires way more pipe and contractor time; oh and whenever possible, keep all incoming and outgoing water lines OFF exterior walls - in your case, ideally underground - and freezing will never be an issue.
I have looked everywhere, can't find my copy of Harrowsmith...but I believe this is it: The Harrowsmith Reader, vol II, from 1980, chicken on cover, around $20 from Amazon.ca - I just ordered me a replacement copy!
I sought in vain to locate an archive of old issues etc. (perhaps someone more clever than me can...), and have emailed the "new" Harrowsmith (the original kinda shut down for a while, not too sure if the new one is affiliated or not). Have tried to research the test build I mentioned, and can find nothing (again, perhaps someone more clever than I...).
There is a cordwood thread in this topic, from about 8 yrs ago, but again, I don't know how to do the permie link thingy (perhaps someone more clever than I???) that mentions Cliff Shockey, who built a cordwood home in Saskatchewan, and this link I believe is for him: https://cordwoodconstruction.org
Then there is good old google, whilst seeking the Harrowsmith info, I found a few items that may be of interest or use.
These might be useful:

Techincally this is for New Brunswick, but they do a good job of outlining the potential pitfalls of cord wood buildings. https://snbsc-planning.com/cct/non-traditional-building/
Here is some local inspiration...perhaps a few field trips are in order?!
Cordwood Lodge Bed & Breakfast in Bracebridge, Ontario. The lodge is a forest retreat, even providing guest bedrooms. You can find out more from bedbreakfasthome.com.
Cradlerock under construction, Ontario, Canada. This photograph was found at “cradlerockhomestead.com/LayingCordwood.aspx”.
Incorporating glass etc., into a Cordwood build...
Cordwood Masonry: https://www.cordwoodmasonry.com/V2/beauty-of-cordwood/
"...Cordwood masonry is an inexpensive, environmentally sound method of building both exterior and interior walls for houses and outbuildings. Done correctly, these walls can also be very energy efficient, combining good insulation and thermal mass characteristics. I cover these points in my two latest books on the subject, Essential Cordwood Building: The Complete Step-by-Step Guide and Cordwood Building: A Comprehensive Guide to the State of the Art.
I am wistful and slightly maudlin; wishing time, age and infirmity had not ended my dream, and yet reinvigorated by my search - perhaps a cordwood shed is still in my future! Good luck!
