Hi there, if you have got any more houses that you can not build, please post them here:
http://discourse.stonehearth.net/t/a14-a15-the-buildings-my-hearthling-will-not-build-thread/14704
In the meantime, did you try to place and build the saved template?
Destroy house,
place it again via template
try to build
Or just use instant build command via console
strg(ctrl) + c
and there type in
ib
while having the house selected.
