@vitusthemad no real set formula but we do it like that to fit human scale. The equator at this heigth makes for a dome that allows for more head room Near the walls and ceilings. It would make sense to make a higher equator as the dome size increases. I know that smaller domes use shorter equators to keep bricks from angling too steeply at the base...
@Kintore Hi, imagine you are in a hemisphere and walk towards the perimeter. How close can you get before bumping your head. This is one of the biggest benefits of the Domegaia solution - you gain all that space under the curve. The other benefit is aesthetic - it looks beaut!
@Samson-Jones If you have not already tried this. I would say aircrete used directly as flooring will flake off a dangerous to inhale dust. So no, I would certainly coat it with a "milk" layer that includes laytex.
I thank you both for the information. As mentioned I don't think there will be much of a load on the steps and the footer under them. I too am in Hawaii--on the Big Island in North Kohala. I want to use aircrete but only if it is 'doable'. I was reading in the some of the posts here, that the use of a 'fabric' adds the much-needed strength to the building as a whole. I'm wondering if it will add some compression strength to the steps and footing if I were to wrap them, once completed in the fabric that is set in 'airmortar'. I am very new to this and want to do more with aircrete in the future, that is why I would like to figure out a way to do this footing and set of steps using it, instead of the 'quickcrete' that I have used in the past for projects. I like the idea of a 1/2" of mortar over everything and even using tile over the aircrete seems like it would certainly disperse the compression load. Any and all comment/suggestions are more than welcome. Mahalo for getting back to me. Aloha...
@Anm8or Hello!!! Thank you so much for your message. I'm really looking forward to work with you to build arecrete dome house in Michigan. I have seen a post with a picture of aircrete dome house by someone from Michigan on this website. However, the person mentioned that the house is only about 200 sqft (if i remember correctly) and it requires a building permit from the department if you want bigger dome house.
My biggest concern is getting a permit from Michigan government.
I have been contacting people who are interested in this project.
I'm trying to build one in Ann Arbor area, but I probably need a building permit also.
To be honest, I'm not sure where to start, but lets do our best and make it happen together!!
Please let me know if you have any good ideas & updates.
thank you so much for your support again.
