I recently spent some time making a aesthetic melon and pumpkin farm. It generates $50 or so per layer and fits in a 10x11 or 10x10 plot with modification to the latter. Pm me either ingame or on the forums with the layer number and exterior material, by default I use stone brick. And no sharing the design if I build it for you!

 

Come on! Does nobody want t see this farm? I buil or in my basement in machupicchu...
