Hmmm. Not sure I know how to pin it down? If I had to say anything it would be 'Organic'?
I like builds that work with the landscape. A lot of my places, even in technical modpacks wind up looking like something out of a botanical garden.
I have a real weakness for the 'abandoned jungle temple' theme as well.
Honestly I just build to reflect my mood, but it's almost never been post-modern.
Cottage, archaic, midevil, classic....
What day is it and what direction is the wind blowing? lol.
