@lukechristensen said in New to aircrete and domes:
@zander would it be better to make one giant done or a few smaller ones
Only you can answer that question. There are pros and cons to both approaches. This question applies to dome homes similarly to how it would apply to any other building method.
Smaller structures are generally easier to build. This is particularly true with domes because they tend to get taller as they get wider. The more work that must be done from a ladder or scaffold the more risk of injury exists. Small structures are the best way to learn any building method. Perhaps the best approach to learning any building style is to first build a cat house, then a dog house, then a cabin, then a small home. Many people can't afford such luxuries of time and jump right into it. That works too.
Larger domes generally cost less per cubic foot, assuming the same wall thickness. This includes the cost of materials as well as labor.
Several smaller structures provide more autonomy and privacy for members of the household. Having multiple smaller specialized structures can better integrate with the terrain and encourage a more outdoor lifestyle. That being said, domes can be quite easily conjoined directly or via arched passages to create a seamless domeplex where each dome may be compared to a "room" in a modern "house".
I am sure there are many more factors that could be considered on this topic.
