Search room shell in decorated rooms

Bundles are one way, but many room creators will make a 'furnished" room which requires little to no additional decorating, or then "empty shells" for people like me who want to put in our own interior design.

Someone gifted me a room like that; it came with 36 furniture items which were already placed. She said that I needed a better room than the starter room one gets for free when  joining this site. She also told me that the same developer created each of those 36 furniture items just for that room. 

I haven't added anything to that room from other developers because it would ruin the décor theme. Almost everything that developer creates; including their clothing seems to be themed to fit in with their rooms/furniture style.

I think it's important to decorate rooms with furniture that fit in with everything else so no single item stands out like a sore thumb. I dislike rooms that looks like they were decorated with an inconsistent mismatch of furniture; such rooms make me uncomfortable in a very unsettling way that can agitate and trigger me.
