This superlight store comes in two sizes.  There are instructions on how to make the doors phantom. The store is two stories with an escalator/staircase inside.    The plain sides are perfect to fit this store into an urban build between other buildings and also would work quite well as a skybox store.  Small store is 34 prims including the doors,  102 prims for the 60 meter store with doors.   You will love your new cyberpunk store.
