Yeah, you could get some pretty cheap stakes put some wire between and grow the Clematis on that if you want to go Clematis way. But I'm sure your neighbour wouldn't mind if you put some brass screws into the posts and put wire between for supporting your climber.
I meant to add to my last statement above about the Rambling Rector that it grew 3 meters in the first year. It's been in just two now and has almost filled or at least softened the large gap I bought it for. It would probably be too big for your space but it would certainly grow faster than anything else I could name. Did I also mention that it has beautiful scent and rage clusters of smei-double flowers. The bees still get a good helping of pollen and nectar. It isn't native though.
Another native with berries and is evergreen is Ligustrum vulgare. Now, the British origin ones are not fully evergreen but the Italian origin ones are. If you go for that one be very careful not to get confused with Ligustrum ovalifolium, the common privet, L. vulgare has berries since it flowers much earlier in its life that the common privet, which is from Japan. L.v. has the same kind of white flowers, smells very nice and attracts bees and butterflies. The berries are poisonous to us but the birds eat them.
If you don' have Viburnum opulus though, I do recommend it. It's so lovely. A bit unruly if you want something formal but I doubt you do if you want a wildlife plant.
