Typical workable layout for low level hideouts:
Hideout Base--Generator-- Glue
Zeronite--Generator-- Lab of Knowledge-- Fighting Bots (or some other singular room)
This places all your rooms available for boosting next to generators. Long term start considering:
Glue Generator Zero (another 2 slot room or two more 1 slot rooms)
As the demands for Zeronite and Glue increase you will need that kind of floor.
The best tip I can give you...
You are going to find yourself needing space or needing a particular room that you cant place because you need to dig. As long as you have the robot warehouse and a good defense robot buildup, sacrifice your defense post. This is a 2 spot build that you can use for other things for the time being. When you can, or you accomplish what you need, store the other rooms and put the defense post back. You will not lose anymore fights than normal as long as you keep your defense bots built up...
