You have a pretty blank canvas to work with and a lovely old looking wall. Keep an eye on that ivy, it can go mad. Monty Don did a programme last night about people's gardens and one of them was in Snowdonia. He showed the guys how to plant little things in tiny gaps in a slate wall. Perhaps you could watch that on iplayer.
What do you want to use the garden for? Do you have toddlers, young footballers? Do you want to grow some veg? Soft fruit? Apples and pears? Do you want to split the space up a bit? A wildlife area? A pond?
Can you give us a photo taken from upstairs, so we can see the whole thing at once?
In the meantime, while you are thinking about these things, have a look at the neighbours gardens, what are they growing successfully? This is important as different soil types support different plants.
You are going to have so much fun sorting out the garden, I'm almost jealous
