A 2d project of a food stall

The stand itself has to be compact. The back wall is supposed to have compartments. We will need to have a small water filter in the back as well as a small sink due to the sanitary reasons. In the front, there will be two grills. Also, we need a small compartment inside where drinks can be stored, as well as sausages and buns. Outside of the booth we need space for things such as tissues, salt pepper etc. The booth itself has to travel in and out of a garage twice a day, so it has to be light and has to have wheels and be able to connect to a truck that will transport it. An important detail is the source of energy in the stand itself, which is the issue that hasnt been figured out yet. As for the materials, probably wood, metal, etc. Colours - We are thinking gray and blue for accent details, but I will be glad to hear your artistic take on the project. I dont have any specific dimensions, I can only tell you that there have to be two grills, one is 24x20 cm, the other is 44x24cm. As well as a solution for a fridge has to fit inside, a sink, and probably a generator, which is usually huge, either under the floor or in a wall. I only need it to fit everything that I have mentioned as well as a person inside and weigh no more than 50 kg
