As it happens I have a number of base game only builds on the gallery. A lot of them I made for Newcrest so they're a bit older. Most of them are tagged #basegameonly iirc.
I also have a base game + game pack only rebuild of Selvadorada as a whole.
My gallery ID is the same as my username here. If you do search stuff on my gallery profile, I've noticed the older stuff doesn't show by default so you need to filter by lot size/price and they'll show up.
Alternatively, you could have a scroll through my showcase on tumblr (my forum showcase isn't up to date unfortunately) - mind though, don't so this on mobile, tumblr works better on a pc.
If I wasn't on mobile myself right now, I'd give more (direct) links, but for now I'll just give my main tumblr link: https://mdianasanders.tumblr.com
As for pack free households, I don't have many (if any) of those unfortunately.
