My suggestions don't include plant picks, but are about arrangement and organization. The plant picks, which you could use regional or shrubs & perennials forums for, are also what will determine winter interest.

An alternate bed line with plants that temper the direct view to the patio is shown.

For winter interest, I'd suggest Winterberry, which has red berries through the Fall and early winter, along with some combination of blue and yellow/gold dwarf horizontal juniper.

Note: for the Winterberry, you need to be sure to get male and female plants to get berries. This is something that is beyond your typical Big Box store nursery. In fact, I got my first Winterberry at one of the nicer nurseries in town, and they never said anything to me about being sure that I also got a male plant. Red Sprite is a good dwarf variety ... which mates with Jim Dandy. Check with a reputable mail-order vendor for best results.

The color in my drawing really means nothing other than a way for you to distinguish one item from the next. You can calculate whatever colors suit your project.

I'd be very careful about engulfing the walk with plants if you want the front door area to seem inviting.

You don't want winterberry under your eaves. They get big and mine couldn't cope with the snow shedding from the roof. Granted, I have a lot of roof, plenty of it quite steep and a tendency to ice up, so your mileage may vary.

Mountain laurel and some rhodos and azaleas are evergreen. They do well in my zone 5 garden.

Your cream/tan siding is pleasant, you could punch up the house with a stronger contrast in shutters and door.

You have a spruce tree that is too close to the house. Its limbs are over the roof and may be touching the roof. It will serve as a squirrel ladder to your roof. Squirrels will explore every nook and cranny they can find, looking for a way to enter the structure. Red squirrels have been known to chew a hole next to chimneys to gain entrance. You must keep squirrels off the roof.

Secondly, spruce needles are acidic and will be a nuisance to the roof and rain trough. Those tend to stick to the trough instead of flushing away during rains. You will be forever cleaning the rain trough, and the acidic nature of the needles will promote corrosion.

During winter snows, the limbs can droop from 1 to 4 feet from snow loads. It will rest on the roof - very bad. During warmer weather, it will tend to keep the roof damp and promote moss and lichen growth - bad.

This tree will only get bigger and its problem grows with its size. I'm sorry to say, but you need to cut this tree. It should have been much farther away from the house.

Spruces do not have tap roots. As it gets taller, it may blow over in a windstorm. If you sanitation sewer line exits from that corner of the house, the spruce roots are avid water seekers and may invade you drain line.

It is nice to have an evergreen out front to have a bit of greenery during the winter months. However, do not locate a large evergreen at the southwest quadrant from the house. It will shade the house from winter afternoon sun, the opposite of what is desired.

Keep squirrels off the roof?? Good luck with that!! And they don't need a tree to gain access. My sister lives in a third floor condo (top level)........it is not unusual to see squirrels racing up the side of the wood sided building......no trees anywhere close!

And large conifers in close proximity to structures is an often overstated concern. Their needles do not cause corrosion (if they did, the entire PNW would have rotted away long ago!). As long as the tree is structurally sound it will pose no problems from roots and the chance of a blow down is remote at best.
