I'm wondering if any other folk spend much time with the 15x20 lots? I'd be hugely interested to see any. My first Sims 4 house was Nookstone - I guess that's the same for many, and instead of moving, gave it a lick of paint and a second floor and it's probably the lot I've used the most. It's easy to expand the existing house there in sensible ways.
Also, I'm conscious of spamming my (few and basic) houses. I can see my user name as the most recent post on too many threads here. It makes me seem over-eager. Seriously, I just decorate boxes, because they're efficient. There must be other cool dynasty houses. And the newest builder can recreate any of these.
So here is my collection of Nookstone builds. (I've also used one of the tiny lots in Newcrest, but that house isn't well balanced, most of the house is underground. No one - not even me - extends the house above ground right into every corner, it would look dumb, but underground it makes sense to use every inch.) This is really a back catalogue. I was browsing through my screenshots folder. Some are redesigns of the same house - so that mini chateau doesn't exist any more, nor does the red brick one.
(My richest sim household, with many millions of simoleons lives here. No need to move.)
This was built for the skill challenge last year. And that means rocket science. I remember wondering what other houses looked like.
If nothing else, I hope someone out there finds them useful, but I also want to see other tiny lot houses.
All of these have basements, indoor pools, saunas, gyms - they aren't missing much. If you start in a small house, you don't have to move out. Okay, the big movie screen would be a problem I guess. But aside from that! And jungle gyms of course. But aside from those, two big things! And telescopes. So like, three things?! Whatever. They're nice okay. Lets not split hairs about if there is space for a "bathroom" or a "dining room".
