I always thought little plaza-like lots were cool, mostly because there are not many (if any) lots in the game designed in such a way. So I built one! This is a Salon and Tattoo parlor built to look like a little plaza.
There's an empty area at the back where you could add a break room or lunch room for when your sim works as a stylist. If it doesn't work properly when you place it in game, be sure the lot type is "Salon".
There's a floor tile in these shots that isn't actually there, sorry :p
It's 20x30, and is intended to go where the library is in Twinbrook, but obviously it doesn't have to go there.
