Timber houses make it cheaper. There is only the concrete slab on the shed and the concrete posts on the house.
Option 1 is to get a guy who strips it and sells off the parts in a demo yard.
Option 2 is crunching it with an 20t excavator.
Guy I use for Option 2 has a big claw on the front of his machine and it crushes it up nice and small to go into the truck so you have less loads going to the tip.
