Here’s my concept art for the modular building kit. I mostly focused on the Mushroom Folk’s house pieces and the mushrooms themselves (which can also be house pieces) since those are the easiest to make modular. I’m considering if I can make branches modular – I did use one branch type scaled and oriented differently during my greybox – but it’s a bit messy so tree parts may not end up being super modular. The mushrooms have a lot of potential to mix and match and be used for different things (scenery, platforms, houses, clutter…) so it’s important I get those down well. I also considered how these people would get some of the typical housing materials like bricks, stone, and metal – they live in a tree after all – so those would probably be less common in this world since they’d have to be imported from a long way away on the ground (maybe wealthy traders have nice stone and brick houses as a status symbol).

Here’s some additional reference images (including one of Higgins House):
