You're worried about offending real world cultures (or, more correctly, people belonging to those cultures). It's worth pointing out that most cases of cultural offense are rooted in the perception that the offender has got something wrong in terms of that culture. They're mis-attributing or misunderstanding something. Something has been used/borrowed/stolen without any tie to it's significance from that originating culture.
This is an easy trap to fall in to when designing a fictional culture by way of picking and choosing from real world cultures. But, this issue can be avoided if you take a different approach to designing the features you want your culture to have. Instead of reverse-engineering them by basing them on real world cultures, I would suggest a different approach.
You are building a world, and you're designing a culture that lives in that world. 846
Instead of basing that culture on real-world cultures, make your culture fit your world. The cultural aspects you seem to be focused on (shelter, food gathering, etc) are all environmentally influenced anyways, so this should be straightforward. If you write your culture such that it fits their world then there's essentially nothing for anyone to be offended by.
In other words, drop the approach of basing your culture on real cultures in our world, and instead base your culture on the world in which they live.
If there's a real world culture that uses adobe brick, it's because their environment and tech supported it. Instead of worrying about whether or not your culture's use of adobe brick will offend a real world culture who used adobe brick, just ensure you are writing your world and your culture such that adobe brick makes sense for your culture. Such consistency is hard to get offended by. And although such an approach can seem overwhelming, since you're taking on the burden of consistency, in the end it's a more organic way to create a believable culture - potential offense aside, the result will likely make more sense to readers in the end than a culture that was just mashed together without any rhyme or reason. 487
