I like it. It seems the sort of thing you might see on Calypso. The folks who critique it looking too clean, presumably there's stuff that can be done in UE5 to adjust the age/feel of a building. Adding elements of disrepair or rust or even broken/missing sections would do that job. Guessing there is something similar to how CE2 could add frost/snow etc to buildings.
I like the modular element. It feels like the sort of thing you'd have for colonising a planet, i.e. build a bunch of key building parts and have them reconfigurable in a variety of ways. The original game had that element where I could imagine the SC's and Delux SC (but especially the SCs) had been dropped there by some large flying ship. i.e. you find a new area, if it's far away enough from everything else, you fly in a shop container and leave it there - job's a good'un.
You could work in an idea of functionality from the start i.e. that each settlement needs some sort of antenna somewhere near by for the transporter network, and maybe this could even be attacked or go offline from time to time. Would give us all something to do
Guessing with the modular walls you could add extra sections that allow for essentially corners or semi circles with stuff in between, So it doesn't always have to be a circle.
The key thing with buildings in the future, is that it would be nice if MA take an outlook from the start of "everything has to be there for a reason". No more closed doors. If you want to put in a closed door, implement a way to open it. You only have to do it once and then you can reuse that functionality when ever you feel like it. Getting access to a building could be a nice soft/free reward for an exploration or story mission for example, i.e. when you are not wanting to give away free money because the mission doesn't involve expensive grinding.
Probably one of the key issues with the game is that there isn't much notion of progression except numerically. It would be nice if doing stuff had a reward that got you into another part of the world for example. Just ideas but now is the time to get them on the table for consideration.
Anyhow bit off piste there with my response to an RFC on a building design
Yeh looks nice. I kinda want to have a stab at building one myself!
Cheers for sharing, especially the nice high res pictures so we can get a decent look at what you are thinking of
