Hi everyone. We've been looking at a few properties and we've found one with lots of potential <read long term fix-up project! [grin] ) Anyway, there is a large concrete area at the back where there was once some kind of outbuilding. It's lovely and flat and a great size but I wasn't sure if you would have to dig up all the concrete to put the sand school in or if you could just sort out drainage somehow and put the school on top. The alternative is to dig into the hill a bit at the side of the house and I wasn't sure what would end up being more expensive. Also, if you have put a sand school in - how much did it cost (appox). Thanks!
