If I was building a new home for myself I'd love some incredible dream home deigned software to help me design a home I love, incorporating a library of ideas, and a community to share a collaborate with.<p>Some smart YC company should build this.
I would love to see it load various zoning laws and as well as building requirements for a particular city and then work within those constraints. There is not a lot of regular sized conforming building lots in bigger cities. In many cases, you have to get a variance from the zoning board before you can even get a building permit.<p>What might be a cool feature also is a renovation tool that can sort of plan what you see on a show like Property Brothers. Given a blue print of the existing house, the tool can help you visually plan a renovation.
Secondlife is good for idea visualization<p>I think the big challenge is getting the wall dimensions right for the hidden stuff, like piping wiring, central Heat/AC, etc.
