Hello! So I've recently kinda given up creating my own houses as I'm never satisfied with them anymore. I'm interested in a blog, whether it be tumblr or just any other website for that matter that specialises in building lots for TS4. I'd like to reference Wondercarlotta's blog as I love her stuff, but I'm after other creators like her too! I'd also highly prefer it if they used NO CC in their creations whatsoever.

someone new I just started following:

and if you are looking for dilapidated no cc houses: ulrick 7 (i believe - look for detroit in the item name)

If you search TheSimSupply hashtag on the gallery, he has a ton of builds. You can also check out his building playlist
