Choice of the land...
The most important !
Finding your ground is the most intense reflection that will induce questions that only you can answer.
Taking full advantage of the southern sunshine is very useful for domes with large windows during the cold seasons.
Having a clear view is a must. Sloping terrain will help you.
Are there any big trees on the ground that can be used?
What are the possibilities of building a dome there ? (considered as lightweight housing that can be dismantled if necessary).
Do you have an easy access to water?
