12' Tree or Shrub for Screening a Neighbour's House

My neighbour's house is set back a lot further than mine, so when sitting on my rear patio, two-thirds of his house's side wall is visible. So I want an "instant" tree or shrub to screen it!

Ideal height would be about 12' with a spread of about 8-10', and an umbrella or fan shape to spread sideways to screen the wall. Can be deciduous or non-deciduous. Really want something quick-growing.

The tree or shrub would only be 9' from the corner of my house so naturally I'm concerned about planting a tree as I fear roots will undermine the house - unless it is a compact root. Firs have compact roots but they won�t provide enough screening.

My only thought was a buddleia as they are quick-growing and I can cut it to shape. Anyone got any ideas for trees or shrubs?

 

Bamboo?

 

Hi Maplewood and welcome. I agree with Fonzie go for bamboo, specificlly Phyllostachys, you can have gold, green or black. And it should do the job you want quite quickly. However, it can be invasive so you would have to keep an eye on it and manage it properly. David.
