Ah I see what you mean, but I'm not keen on raised beds and the level needs to come up about 200mm anyway so plenty of capacity for good stuff. I actually heard a bloke on gardeners question time saying how good clay can be if you just add enough organic matter, which chimes with my experience at my allotment where I've much better soil on the half I've added more to and still muddy or rock hard on the half I haven't.
I think the huge oak at the back will soak up a lot in winter if I can move water in that direction.
There are definitely advantages to it for water retention. We have actual clay in our soil. When we had our patio done I made models and pots with my kids out of lumps in the skip. So in some of my pots I've put some lumps in the bottom to help in dry spells.
