This is a re-creation of Jessie's Tree house from the beginning of Minecraft: Story Mode.

One thing I found out quickly while re-creating this set is that the camera in Minecraft: Story Mode compresses space. So while it might seem tight and small, the actual environment when built out block for block is actually quite open. This is likely due to the fact that these are sets for 3D "actors" to interact in, and the camera needs to be able to get around them and find the right angle.
