Making certain buildings or houses isn’t hard if you have the time and practice in doing so and put some effort into it, such as learning the software searching and using different methods to accomplish a detailed cartoony house.
We have a few resources and tutorials hanging around here on the dev forum and there are definitely some by doing a quick search on the web.
I wouldn’t go into more detail since there’s hundreds of videos already here and out there try finding some simple tutorials if your new to making shops, houses so on and so forth here is helpful source you could use to get started.
