Abstract: A modular convenience store. The store has a floor and a plurality of walls extending substantially vertically from the floor, which define a perimeter of the store, which has an interior and exterior. This plurality of walls includes a front wall, a rear wall, a left wall, and a right wall. The front wall is less than or equal to sixty feet long. The rear wall is less than or equal to sixty feet long and substantially opposing the front wall. The left wall is less than or equal to fourteen feet long, and the right wall is less than or equal to fourteen feet long and substantially opposing the left wall. A roof covers the interior of the store. A front door is substantially intermediate the front wall, and a rear door is substantially intermediate the rear wall. A walk-in cooler, with an interior, is located within the interior of the store, adjacent the left and rear walls, left of the rear door, and spaced from the front wall.
