I have a very small back garden in my new build townhouse garden. We have a very small patio and then a lawn area. The lawn has just been removed and the soil rotovated (due to builder's rubble left behind). We are going to re-lay the lawn and create a flower bed on one side next to the fence. I would like ideas for how we could create any kind of striking and pretty look in this kind of limited garden. It isn't very sunny where we are going to plant. Another problem we have is that the garden slopes upwards! We want to move in the next year or two so nothing too expensive?
