How to make high quality interiors?

[parzysty]

I'm interested in making a high quality interior, similar as the one on the screenshot (ignore the girl). Or maybe someone knows where is it from? What CC to use to create a realistic home?

I'm not sure about this particular pieces of CC, but there is a lot of alpha (realistic) furniture and decor at https://www.thesimsresource.com/. 

You can download whole rooms or houses from this website, just make sure you downloaded all the CC required for it to work first.
