>>509616773 (OP)If you build using modern gravel brick like this which is full of tiny air pockets, they are extremely good insulation unlike wood.
So especially in cold environments, but also in hot ones, the savings in energy costs are absolutely massive due to the humongously better insulation it provides.
Not to mention modern brick like that lasts hundreds of years, wood only lasts long if you use old growth wood and don't cut it but make it in the log cabin style, and it still doesn't last as long, especially in warm and humid environments.
And like the other anon said, generational wealth. You can have the grandkids of your grandkids inherit the house that you built, and have it still stand.
