Do u have a city and want a marketplace, or maybe u just want to have this in your map? Well, here is a simple market stand for u. (If you are new at building or just don't want to remember how to build it, you might wanna read the steps.) (I'm sure most of you can tell from the image what to do.)

Place two wooden guard towers, as shown.

Place crates on the edge of the towers to roughly form an arch. You might need to look at the image for this one.
You can overlap crates on each other.

Place a metal table in the area that is left. Then you can conect the edge of the table to the arch by adding another crate (it can overlap the other crates.)

Now you can place equipment on the table, and maybe a unit running the shop.






Sorry if this guide wasn't good or helpful, this is my first guide.



NEW UPDATE!!!! NOW YOU CAN USE A WOOD TABLE INSTEAD OF A METAL ONE!!!!!!!!!
