@HandyDan ! We're looking into 2 canvases; the inner canvas has edges that can carry insulation.
The outer canvas (poly-cotton or poly-hemp) can be very colourful.

Interesting! Will study. :-)
Yes, aircrete is great for casting in moulds. I've researched all kinds of existing moulds and have found some interesting and inexpensive ones in India, used for temples. :-)
I also found out that you can use computer cut Expanded PolyStyreen (EPS) to create sophisticated moulds.
Then I also like sacred geometry, access to nature (also in cold climates), and the possibility to move the entire structure (like a yurt), which is possible with bamboo (you can just load an entire dome in a van) and a tunnel greenhouse kit, which at the same time solves the door and light problem of the domes, as the greenhouse lets in lots of light AND serves as temperature buffer.
All this is quite inexpensive, quick to build, eco- and people-friendly.
But what to use to cover the bamboo skeleton?
Hajjar actually gave me the idea to use a 'dome fabric' with a beautiful design. This is perhaps good for a warm climate, but I'm looking for insulated versions — or perhaps layers — for where it gets cold.
I think I've found a company that is willing to produce such 'dome comforters' with 7 integrated round windows (for the first floor which mainly serves as bedrooms) and 2 openings for the greenhouse and a large window. Re: natural materials there's still some research to do, and I have no idea yet of the price.
It should be possible to quickly tie the comforter to the bamboo structure with velcro straps.
I believe in community and co-housing, but I also believe in enough privacy for all participants. The structure I've posted, made up of 2 or 3 domes, is a community center.
Around it can be stationed various tiny houses on trailers.
Both the community structure, and the tiny houses are mobile, therefore don't require a building permit.
Lay-out, and especially size. My domes have a diameter between 8 and 12 meters. Hence also the difficulty to make them in aircrete.
We are using bamboo for the skeleton structure and are currently researching a sort of insulated damp open skin with 7 built in round windows at the top, which would give sufficient light for activities on the second floor.
On the ground floor we use the greenhouse connection as main access to nature and light.
All suggestions welcome. :-)
I have to reply to this. :-). I also miss a more lively, interactive forum and especially some sort of shared vision.
Hajjar's video does explain a lot, but it's clear to me that the aircrete domes from Thailand are not suitable for colder regions in e.g. Northern Europe. We also want to pay more attention to big, but not expensive windows, that allow us to blend more with nature. Connecting 2 domes by means of a tunnel-greenhouse seems like a good idea to me. One dome is also not enough if you want to live in a colder region, where you are inside a lot, so it makes sense to build at least two and connect them with fairly inexpensive greenhouses (the tunnel variations are curved) that bring in a lot of light, and at the same time the possibility to grow food, live and work in a more veranda-like environment.
