An assembly hall (town hall). The reason those churches get used for other things is that there are reasons other than worship for everybody to gather at times. A church's main hall is only in use for a few hours a week, so gatherings at other times are feasible. Your need for those gatherings doesn't go away just because your society doesn't have ...

Future space colonists should aim for the lifeless rock. Problem with alien biochemistries is that they might be immediately hazardous (anaphylactic shock after a lungful of the local air) or maybe its just filled with stuff that causes horrible birth defects and chronic brain damage and your brave new world is going to turn into a hideous and drawn-out ...

Every society needs to have multiple functions, so if you can only build one building for general civic use, it needs to accommodate all these functions You cannot just focus on one purpose for one building, you need to incorporate as multiple functions as possible. This is because if you group more than a few people together, they need to: Governance: ...

Unfortunately, I suspect the best choice is Start with a living world, then kill it The dead worlds are unlikely to have water and breathable atmosphere. The living worlds have, well, life — at its worst, deadly on contact, at its best, kudzu and mosquitoes and funguses that eat rubber seals. But if you can hit the planet with neutron bombs, you can kill ...

Since we are talking about a space environment, the actual first public space will be the radiation "storm shelter". This will be an enclosure somewhere near the center of the colony structure so the bulk of the colony itself will provide the first layer of shielding, and the inner structure will be heavily armoured with thick metal or regolith walls to ...

No tools to build tools. The surviving ships had a limited supply of spare parts and no means to make more. Once the capacitor on the ciruit board of the 3D printer goes bad, that thing is completely useless. Perhaps the engineers realized that, and tried to 3D-print old-fashioned turret lathes and printing presses with the starship workshops. But then ...

Either a Courthouse/Jail or a School The determination as to which of these would be built would depend mostly on the characteristics of the population. If they have a lot of children (mostly families, farmers, etc.), then it'd be a school, if this is a mining town (a bunch of bachelors) then a Courthouse/Jail. It really just depends on what they need most....

You will have to make assumptions about the likelihood and severity of problems. The best case would be a highly compatible biochemistry. You can assume that the choice of amino acids and the chirality of organic molecules in terrestrial life is not random, but rather a subtly optimal combination. The worst case would be an incompatible biochemistry. ...

Given the random element driving evolution and the multiplicity of possible chemical out comes it must be highly unlikely that an alien biosphere would be hospitable to life from Earth. There is every possibility that different bases, sugars, amino acids and many other novel unfamiliar compounds would have evolved. Some probably harmless, some less so and ...

It would be unbelievable if they had kept their technology after several unplanned and under-equipped diasporas. Advanced technology is not just a bunch of technical lesson plans which can be casually carried along in every ship's computer. It is also the undocumented wisdom of experienced practitioners in hundreds of distinct disciplines. Beyond that, ...

It would be much easier to colonise a living world. Non-living worlds do not contain much oxygen or products of a long chain and a long time mulching through various substances. Living worlds mostly got that covered, although different products might be toxic cross-ecosystem. So. Scan for biocompatibility and toxins, Prepare substances to bind/remove ...

Your premise already explains it. and those who survived were dispersed on a few dozen smaller ships that scattered themselves throughout this new galaxy, with each eventually finding and settling their own uninhabited new world. The large knowledge databanks, the educational material etc., would have been in the mothership alone, of course. The smaller ...

Since distance is rather important, division based on Voronoi cells seems appropriate. Perhaps with modified metrics/topology based on "jump points" or whatever. This however won't give you equal volume cells without some modifications.

How Goldilocks? If a planet lay in the Goldilocks zone but doesn't support life, why is that? Lack of water? No magnetosphere? Too many asteroid impacts? Metal poor? If life isn't there already, the conditions may make it hostile to permanent settlement. If life is present, then at least something was able to adapt to the conditions. If you have ...

Sports field. Sporting events are great entertainment and a fine way to bring a community together. Having sporting contests with other local small towns is also an opportunity to mix with people from other small towns which is especially good if your town has no cute people in it. Ample raised seating for spectators makes the field suitable for open ...

I think the very first thing to get built would be a Well. Even if there is a nearby water source like a river, that same river may dry up in the summer and freeze in the winter making it's use impractical. In addition, rivers flood sometimes, so building too close is not always the greatest idea. A Well, is not what I think the OP is after though. As ...

There are some interesting ways in which gravity has been talked about in sf without the magic of "Grav Plating" ;-) First, there is artificial gravity created by motion/spinning a hollow object on its axis. Probably the best examples of this perhaps the hollow metallic tube of Rama. More recently The Expanse gave everyone a glimpse into space ships that ...

Use a set of spheres-of-influence around points of interest, rather than a single sliced sphere This suggestion challenges the OP concept of dividing the entire sphere into sectors, offering an alternative which can be explained using in-game logic and is comparable to the way real life international law treats territories, territorial waters and ...

Depending on the age of your settlement it is possible they would use a re-purposed building. The Old Dormitory Immediately after landing everyone needs somewhere to sleep. Can't sleep in the ship, it's already left/we were in cold sleep/it's being dismantled. So first things first we run up a big barracks type dormitory. It's got bunk rooms, a kitchen and ...

A General Store In most towns, this was built privately by whoever had the capital to build the building and then was the first to set up the store (which takes a fair bit of money to stock). A town served by a railroad is the standard here. In a town without a place of worship, they would still, as Monica points out, need a place to assemble, but it's ...

A living world is strictly better. But you will still need to live in airtight habitats. You have an atmosphere that has a reasonable pressure. This means your dome doesn't need to be all that strong; you're not trying to keep the dome from collapsing or popping. You probably have a reasonable temperature, so your habitat will likely be easy to heat ...

The people who survived aren't useful to keeping tech running. In the Hitchhiker's Guide to the Galaxy series, the people who crash landed on earth were not...exactly pioneer material. They were mainly middle management. If the majority of people who went down were ordinary citizens, most would not have any technical expertise, let alone be able to figure ...

They choose not to use their technology Given that your story starts with humanity's reckless use of technology destroying a planet, I could easily imagine a new colony making a deliberate decision to regress to pre-electric technology levels, or even further. Give it a generation or two for the old education levels to wane and you have your technological ...

The problem is going to be to make them lose some technology, but not so much as to prevent them from surviving. Mesolithic people had their own technology that was very effective for small hunter-gatherer populations. They knew how to make tools and hunting weapons using local resources. They knew which parts of which plants were edible, and which could be ...

I feel that the premises of your question are somewhat unrealistic. Firstly, radiation fades very quickly. https://emilms.fema.gov/IS3/FEMA_IS/is03/REM0504050.htm In that source, it says "for every 7-fold increase in time after detonation, there is a 10-fold decrease in the exposure rate." In a few weeks or months after the detonations, survivors will be ...

Geomagnetic Storm If the planet where they settle down is in a similar solar system as our planet, then a geomagnetic storm is a way to make them lose all of their electronics in a short time. If you check this article you can learn more about it, but according to it says: A geomagnetic storm on the scale of the solar storm of 1859 today would cause ...

Only the kids survive. The adults die within the year after arriving on the new planet. Just as adults who catch measles can become terribly ill but kids shake it off, the adults fall victim to disease organisms endemic to the new worlds while the kids roll with it and emerge from infection scarred but intact. The little kids who are the main survivors ...

as far as i read and grasp of the list, most non native Eyjagard animal wont screw up the native species, base of my observation from my own country (majority of it is livestock anyway, they are everywhere including tropical country al though some generate different trait or adaptation). except cat which as far as i know has extinct/endangered several bird ...

Take your inspiration from buildings made for various purposes. In your search I would consider: Churches Monasteries Community arenas Day schools Boarding schools Frat houses University dorms Hotels Ski Resorts Fishing Resorts Soviet cold ware era apartment houses. Israeli Kibbutzes. Each one has a different impact on how people live together. Also, a ...

Colonialism is built upon a solid foundation of military force. There's a reason why so many of those frontier towns have or had names that start with 'Fort'. At the very least you're going to want a parade square, which is convenient for all sorts of things.
