Area that needs Concrete

We have an area in the corner of our garden that I assume had a shed on it, there is existing concrete which is different levels, only a couple of cm height difference. We are hoping that a new layer of concrete could be poured over the top so we can use this area for seating. The area I think would be about 12 to 15 square meters and is relatively level. Not looking for anything fancy, would just like to have it looking tidy.
