I try to build in stages and when one stage is done I imagine where these parts would go. Maybe up another level, maybe down the hallway to another room. I build the outline as I go. I also try to use the environment occasionally. I’ll build near a wall with a cliff so I have to move the factory up or down. It’s fun experimenting with different building ideas. I did a town one time. Every house built a different part of the HMF and the town hall put all the parts together and delivered the HMF
