Planting trees

I have recently moved into a new build in Stirling and the back garden is laid to grass with fencing all round.
I would like to plant either trees or shrubs against the north fence as there is a fairly busy road and roundabout a few yards behind it.
Don't want the barrier to be too high, around 7/8ft perhaps. It is also a windy corner. I would like something attractive and evergreen. I don't particularly want conifers but as we have a soggy soil could it be advantageous as the conifers would soak up a fair bit of moisture? I was thinking something fast growing.
Can anyone advise on an attractive barrier 12/13 metres long I also need advice on how and when to plant so it's a tall order.
Many thanks

 

Serene, I think you will have some response if you re- post this in the Trees topic as not everyone would look in this - the Hobbies.
I am not much help with trees.

 

laurel, my personal choice would be spotted laurel (acuba)
