A portable barbeque can be yours for a lot less than if you would buy one in the store. The materials for this one costed me around 4000 swedish kronor, or around 600 US dollars.
Step 1: The Base
First we need a base, it's optional how you want to build it but I decided to have a cupboard to cover the sink and bucket for wast water.
I put two wheels on it to be able to move it. But I recommend to put another two wheels on the other side because it will get very heavy with the concrete top.
