The very latest project (kind of a mini-project) is building a rooftop water tower for the new 5-story building above. Unlike my previous attempts at semi-scratch water towers, I'm going to try and make this one more scale and more out of scraps/random parts. We'll see how it turns out... but worst case, I am out $0.
Here's an infographic on what I'm using to build it:
..and here's a a real rough look at it assembled, before some trimming and before the roof and other components are painted:
