Update

Okay, I've managed to finish four out of the six platforms. I hope to finish the last two platforms this week. It's starting to come together. I'm still working out how to implement the arched roof top. Originally I was thinking of making the truss structure out of sheets of plastic. However, I've had a change of heart after working with the platforms. There's no way I would be able to cut out identical arches using the sheets. I would go mad. So now I'm considering using skinny styrene tubing that I can bend into the arched truss structure, but I would need to build a jig first.
