Background: My settings world has sentient life around the space-faring level. The problem is that the planet itself has very few natural resources available, they’re too deep down to harvest or simply not there.
My current idea was this: Even though they’re incredibly advanced the lack of resources mean they rely heavily on the world around them. Using things like woods, stone, or mud to build houses/weapons/tools since what we build those from need to be used more sparingly there.
EDIT: Most metal ores (iron, brass) are extremely hard to mine and even so there's probably around half as much of it compared to Earth. There's also a lack of good sand and rare earths for ceramics and certain electronics. But there's a heavy amount of precious gemstones; rubies, diamonds, and quartz are all exceptionally common. (For spaceships, while they may have them they're from other species, traded to them for the rare gemstones.)
Question: What would their cities/communities look like?
(Please tell me if the question seems too broad or could be improved. Thank you in advance.)
