IGS building

Anyone heard of igatructure?
Are they truly sustinable?
Does this really fit into the permies concept?
We are thinking of building a home for our family.
Our first choice is off course the earthbag dome or strawbale, but we find it so difficult to permit those structures in Southern California, and also impossible to finance to build or in the future there is no chance for someone to finance and buy from us.
Now we are looking into a small house plan using the igs, anyone have any experience or tip or idea? Thank!

My only issue is with the glue. Straw bale houses don't use all that glue. Rice straw is readily available where you live, and it has proven very effective in producing Straw Bale Homes.

I could not find the type of glue in the MSDS or much info on materials. Impressive factory and use of straw, however, low perm glues, foam, vapor barriers will not handle moisture well. If it is OSB/FOAM SIPs construction there will be issues at the seams. Crazy how the industry thinks glues, now to get air seals, will last the test of time.

IRC 2015 has strawbale code you build to it and have it inspected by the local jurisdiction or hire a third party, or get an Engineers stamp. At that point the banks should fund it but may want more down ( which should be on less than mainstream cost) since it is new or an "alternative" building material/method. Most banks just send out an inspector to make sure the money is being spent properly and don't get into the tech, especially if being built to code or stamped drawings.

Bag construction is basically concrete per IRC code.

You can also get assumable loans to make selling easier.

Much of funding is how it is communicated, and how to negotiate creative financing. Check into hard money lenders too.

Welcome to the challenges of being a natural builder

Watchya got in that poodle gun? Anything for me? Or this tiny ad?
