What plants could i use?

Hello all.

I have recently moved into a new house with a blank canvas of a garden.

One of my requirements, is the 8x6 greenhouse, which i would like to shield from veiw on the two aspects facing away from the arc of the sun.

I am looking at planting a row of bushes/trees that would provide something like 2-3 foot horizontal growth, and circa 6 foot vertical growth. Ideally these should be relatively attractive and have foliage for a large part of the year.

The soil is pretty good, with good drainage.

Has anyone any suggestions on what could be a good plant for this purpose?
