What am I going to do with this?

Our new back garden.
It's a good size, not too big and not too small and as a plus point instead of looking directly at the side of another house there is a green belt area behind us, which has fields behind it. (Unfortunately at some point in the future there will be houses built on the field, but hopefully we won't be effected too much by them)
I have some ideas of what I'd like to plant, but that may need to wait until next year as we'd like to get the house sorted first.
