I love the potential this game have but I think adding much more domes will add new and interesting ways for setting up later on game play because survival is not everything. So lets add some fresh and interesting ideas for developers and future mode creators to take from please add as many ideas as you can, here are some of mine:

1. Prison dome
Simple dome that will allow housing of space prisoners send by space police, they will require food and water, will lower prestige of your colony as no one wanna stay in the prison colony they will generate daily income and depending on what facility are avelible to them will riot with low moral. Riots will have to get put down by your security force with stun weapons as each killed prisoner will cost you a lot of credit. You will be able to chose what facilities are prison facilities so you can share existing assets and put prisoners to work.

2. Medical dome extention
Range of injuries that can happen in place like space colony is crazy and putting somone in bed and giving him some herbs might be good for common cold might not help when is coming to radiation poisoning. Adding radiation showers, nursery, operating tables, organ and limbs 3d printers, first aid bots, contamination rooms (imagen damaged simple flu can do in close environment like that) , adding new and interesting injuries will allow you to decide to make space hospital space events like war or pirate attacks will keep steady number of patients coming .

3. Garage
3 Sizes garage with room for simple space buggy , bulldozer that will allow editing map , and logistics vehicle that you can load up with cargo to fix some equipment or transport from to space port.

4. Sanitation
I don't know what filters the air purifiers have but we need some showers and water recycling plants. If you dont have showers moral go down and chances of epidemic go up, if water is low you can get denomination showers that will use power instead of water but with some form of safe radiation eliminate chance of epidemic (decries moral more as you get that microwave taste left) . Water recycling center will allow you to get some water back instead of pumping fresh water all the time , also give option to buy water for new planets with low or none existing water supply, water will be hardest resource to get out there I think they need to put more attention to it.
Recycle equipment will allow you to turn some garbage and waist in useful products, working in this places will lower your moral so you will wanna staff them with bots or prisoner and eventually get fully automated versions.

5. Gambling
Room that will allow visitors and staff to spend their hard earned credits.

6. Kitchen
Automatic food staff is all good for prisoners and start but once you get your place going it will be good to get some real meals going they will waist some food but give you moral boost better the cook better the meals plus will boost your reputation more that space banner and attract better visitors. Plus I will love to see Elon Musk pizza place ;)

7. Lab
Lab will not only research new equipment but also find cures for new space sicknesses improve existing equipment and plants boost your medical staff by diagnosis you will be able to chose do you wanna go more in biology or mechanical letting you improve bots or colonists. Running experiments on prisoners or unexpecting visitors.

8. Pr. Center
Slowly working your reputation up and making sure that last scandal don't damage it too muche.

I think some of this ideas will give you more choice of how you wanna your colony to look is it 4 star hotel or medical center or maybe prison mine colony. I cant wait to here some of yours ideas.
