My BP Store build will be on early release this month. Here is some of the custom content I've created:
street lamp
cig set (LED lit 7 swatches)
pumps
awning
signs
soda/coffee machines
walls/floors
simretail counter set
Java Bean Cafe Espresso machine/cups & signs, counter
& even more coming. This will be on a 50x50 lot. I have personally never been to a BP (British Petroleum), so I rely on images from several locations and my own imagination in creating this. If you think anything else should be added to this build, please let me know in the comments.
