Tree-house Research

As part of my environment, I wanted to add a central location to it, after some research and thoughts, i decided a tree house would do the trick. A tree house would be fairly easy to model on Maya as well as a tree as we've been given a tutorial on how to model and texture a low poly tree. I gathered some images of different types of tree house that would look good with my environment, I've shared a few below:

Most of these ideas would be manageable to model and keeping the poly count low, but i don't intend on creating an overly large house, I will keep it manageable.
