Thanks for the reply, have decided to slow down and try a mixed hedge of different plants. Will include several lilacs, a spruce or 2, some deciduous shrubs and trees, a mix of evergreen and deciduous. If the dust gets unbearable in the meantime we'll have to put up a solid section of something like fence for the short term while the plants mature. Thanks for the help! Snows.

You are definitely going for the right look for a foundation planting, namely a layered series of different textures with evergreen at the back. But I agree that a total of 5 feet from foundation out is not enough width to get that job done. You have enough sun to work with and you have a vision, so why not do it up right: expand the bed 3-4 feet, move the roses out a few feet, and then put in some spreading yew or a globe arborvitae-type thing about 2-3 feet out from the house. You'll have to trim the yew or whatever you put there, but it will give you the look you want. Yews are incredibly overplanted on the foundation, but for the back row of a layered planting, I think they work just fine. Put a low layer in front of the roses, maybe some Blue Star Juniper, then you can keep the layered thing going on during the winter. The Blue Star is fairly slow growing, (especially living on the east side), so don't expect it to fill in quickly. Instead, cough up the cash and plant several. If you think widening the bed is daunting, just lay down wet cardboard on the turf and cover with lots of mulch. Then cut out wide holes for your plantings. The grass will be long gone in a year. Boxwood could work against the foundation too, but it grows like molasses. Just my thoughts, based on having been in a similar situation. Get what you want the first time around, so you don't have to do it again later.

I have bamboo that I'm trying to kill. It is the runner type that s all I know. Its pretty invasive and I'm always cutting it back.

EDIT: I TOTALLY MISSED THAT YOU'D SPECIFIED ZONE 4 - MY APOLOGIES, there are a few Zone 5's I suggested.
