I grew up playing The Sims so my ideal housing situation is essentially the same as your comment. There are companies that build custom manufactured houses, like Carina Construction[1] in Ithaca, NY. I haven’t looked into how modifications like those you mention might work, but the prices are competitive and the modular customization is pretty extensive. All-in-all a good deal, if you don’t mind a house that looks slightly plastic. [1] https://carinaconstruction.com https://carinaconstruction.com
