Privacy? Is your home on the left like the neighbours shown? Privacy from what angle? Does it need to block out the view from upstairs windows out of shot to the right or what?
You can get a list of plants for a spot from crocus, especially if you know your soil type (acidic, chalky, heavy clay, sandy or "haven't a clue" but "soggy" isn't an option):
"Perennials" i.e. small stuff:
"Shrubs" i.e. bigger stuff:
3m dogwood and laurel and the taller types of the 1.5m-4m hydrangeas all look like candidates for privacy, with some of the smaller ones underneath for extra colour.
Bear in mind that the more your big plants screen you from a view from the south the more they shade the soil north of themselves, and beware making your home and garden gloomy. I'd start by standing something tall on that plot and sitting where you want to be out of sight then looking at the viewpoint from which you want to hide and marking how far up the pole your plants need to reach to hide you.
Also bear in mind that a 4m-high shrub is not easily pruned.
