Looking at images
online, manzanita seems extremely small and twisty. You can certainly build with it, but would probably be best off gravitating to more organic forms rather than rectilinear ones. It might be well suited to "wattle and daub" construction, which is essentially a semi-woven frame of small sticks and laths with
cob plastered over it on both sides, interlocking to make a sturdy wall. This would require good weather protection, foundation walls high
enough that snow or rain don't splash off the ground and wet the base of the wall, and an overhanging roof that keeps direct rain off the rest (known as a "good hat and boots".)
What sort of house do you want, and how large? That will influence how suitable manzanita is for your
project too.
