Sometimes I sneak in on Black Liquid site and take a peek.
I think it is a good site, although centered around CC and MM.
But I thank you for giving me a hint. I have been testing
different combinations together with the Plimoth houses.
My Colonial houses mod works fine and there I have all those
upgraded buildings I need.
I will model one or two more Plimoth houses and then I see
if there really is a need for more.
And yes, I will remove all stone required to build the houses.
Then it's really a 'starter kit'.
Plimoth houses are just that - houses (and maybe storage)
so it is not necessary to 'invent' new things.
BTW. Vanilla buildings work too. They blend well with these
grey wood houses.
