The 'playhouse' in the top left is a fairly large summer house, that is the problem with pictures, I know what it looks like around the camera but viewers will not. Good point.
Yes, if you stood on the path looking at the summer house, you would have your back to the house, which is a bungalow and a couple of feet lower than where I am standing taking the pic So does not cast a shadow until late evening.
I agree that where I was stood may be a better area but the lawn left of the path has to stay as it is. The dogs and grand kids and she who must be obeyed have made that very clear lol.
So, to confirm, if you stood looking at the fence, you would be facing east, making the fence west facing.
As for flowers. That is a secondary project. The garden is boring and as part of a long term plan, I hope to create some borders, a rockery at the top of the garden and make the boring square of grass interesting.
having said that, I have no idea how I am going to achieve it And it will be (very) long term.
