Imperial-Themed Hybrid Circular Base. Cassandra, Adventure Story, Very Large Map. ~20 colonists and 5 years in-game. Decided to challenge myself to build something not square. Not finished, but please
No roof! If you look closely, you can see I put one square of embrasure in the wall around each geothermal generator. Keeps the enclosure designated as outdoors and prevents pawns from building a roof over them.
