You could have Photinia X fraseri 'Red Robin', that provides all year round interest with its red new growth.
I agree with Busy-Lizzie, you could place some trellising and plant a fast growing climber. If you do not want to spend the money on trellising, then there are climbers like Cotoneaster horizontalis (that doesn't need the support of a trellis), which provides all year interest; flowers spring time, in leaf during summer, red leaves in autumn, berries and herring bone structure during the winter. Another climbing plant you could have is Euonymus fortunei, which has variagated leaves - I am not 100% sure how quick these last two plants grow, though it's just a thought
