Any suggestions to build a 'screen' along the wall in my back garden to
hide the neighbours?

They're indulging in gazebo, pergola, the works, and because the gardens
slope upwards away from our houses you can see (& hear) everything they do.
(They've even got wind chimes to stand duty annoying us when they're not
actually there themselves.... )

There's already a 5' high panel fence, But I need it to be about 50% taller
than it is, as their erections are much higher than the fence.

I was thinking of say a hedge or row of bushes that grows quickly to about
8-10' and stops, needing minimal maintenance? Would need to be along a
distance of about 10m (5 standard fence panels and come in a line alog the
garden edge right up to the back of the house.

Obviusly want to avoid leylandii, and looking at the FAQ the options
suggested a
privet
laurel
camelia (not sure what this is)
clematis

But as a non-gardener, without much time to spare, which is best to let me
achieve a decent screen , ideally within about 6 months without too much
cost?

There is already a single clematis (I think - it's got great big flowers)
there so perhaps the best is a row of these? I would prefer a screen that
still works in winter as I want to avoid seeing what they have in their
garden all year round.

Back of house faces south, garden slopes upwards away from house, located in
Exeter, Devon.

Can anyone suggest the best options to look at?

thanks
