An old tree house I had built around the late 1.3 range or so. I recall basing that off a build in r/Terraria, but I can't find it for the life of me and it's been a good few years, so that's one of those where it'll look familiar but it's tough to source.
Love this house! The entrance, especially. Are you able to get to the area down below somehow?
Yes actually, the right side has a teleporter, which leads down below ^^
