If this is aimed at me, its not that I believe the act of creating generative architecture software is trivial. Perhaps too flippant above. I believe it is probably quite challenging. Which is an excellent reason to create such a software, because it's much harder for someone to quickly steal or release a competing product. I was only surprised someone was not immediately using this thread to advertise their house generator.
“Quite challenging” is an understatement. The problem is far too big for the tech startup model. You would need to get a bunch of expensive skilled engineers, and a bunch of expensive domain experts (from many domains, since “building houses” is a massive problem space with thousands of sub-domains), and work on it for probably years before you had an MVP. It’s not the type of startup that easily attracts investment.
Even if you could find investors,I'm not sure you'd find any customers.
Firstly, only a tiny fraction of people are interested in building a house. And the number that build 2 are a rounding error.
Developers already have architects on staff, already have libraries of plans, why would they pay for this?
Then, every detail of the generated plan would need to be checked. Every. Single. Detail.
Most people who build a house do do because they want to make a mark, or they need something they can't find. They are all literally edge cases. They'll sit with an architect for hours trying to get that dream out of their heads onto paper, adapting to limitations of budget, planning approval, local regulations, budget, site, budget and so on.
