This is a small starter, furnished for 1‒2 sims with a small empty spare room. It is very sparsely furnished to keep the price under 20.000, but all of the basics are included.
Installation: Unzip and put the package in /Mods.
See here for how to package lots (this works the same way for sims). To uninstall, delete the package ‒ if you “delete” a lot from the Library, it is only being hidden and will remain hidden if you decide to re-download. See also this post (same thread):
Lot Size: 15×20
Lot Price (furnished): 19.990§ (including a 15×20 lot)
