It's been a really long time since I posted any updates here, apologies I should not have forgotten my login details.

Although you could combine it with the previous template to make a rectangular building, the possibilities are... well not endless, perhaps twofold!
If you'd like the new template it's available here, with more tips and details into making cooler:
And all the legacy templates are available here
