There are 3 rabbit hole type lots which look really nice looking so you may want to replace existing ones in the town you are using.Cause they are neat
A school
A cafe/bistro
A grocery
Those type are where all the other rabbit holes are located
The lots you can edit or just plop down will be in your library under community lots
A 30x20 gym (Good build just yucky color scheme,few tweaks it is great add any new stuff like chin up bar etc)
A 30x20 library (lazy build in my opinion I do not like it)
A 30x20 laundromat (I do not like it,would be best if you made your own)
A 30x 20 park (Is actually a cute build, I recommend using it <3 )
