Knock the base out and fill with soakaway crates?

Was my first thought. Too many corners to turn for conveyor belts I think. I mentioned closer than 5m to the building as I thought this would have an impact? Soak away must be in excess of 5m from dwelling?

 

Sorry OP for going off topic.  I will be back for help if we complete on the purchase though
