Thanks! It started out as a one room, ground floor shack and kind of grew as necessity dictated. Next up (no pun intended) is to swap out the wooden side pieces for concrete but leave the wooden floors inside and wooden decks outside.

Strongly recommend, in general, to build a main floor at least one level above the ground. Otherwise the occasional terrain regeneration can be a pain when a grassy hill shows up in the middle of the floor one day.

General hint: The corridor pieces (straight, curved, 90-deg, etc.) will mate to the basic materials (wood, concrete, metal) on one end and the traditional round or cuboid rooms on the other. Makes it possible to build with the basic material pieces and still have, for example, a biodome or two for plants.

You can also drop the specialist terminals all in one room when using the basic material pieces. They just need to have their own floor section. Saves having to construct 4-5 separate round rooms to house them.
