I want to create a complete house in sketchup make 2017 that everyone can use. This includes electrical, plumbing, ac/heating, etc. This would include every applicable regulation for where I live in north texas. I want to seperate each phase of the build by category with BIM data for project management. I want to make a website that has pricing data using different materials. I might just be happy with a spreadsheet, but ideally everyone could use the model and download different versions of the house with different prices.
It seems no one does this since everyone who makes homes does it for a living. It goes against their business model.
