Do you want maintenance-free plantings that look good all year? Look for low-growing evergreen shrubs either coniferous, or broad-leaved. If you are open to some maintenance you can include deciduous shrubs that benefit from pruning every 3-5 years or so. These tend to offer more floral interest, though they may be bare during winter. Be sure to note the mature height and spread of plants when you shop, because the term dwarf only means smaller than the species. A shrub with a mature width of 5' should be planted 3' away from walls, fences and pathways. I have no idea where you live, so cannot give specific plant recommendations.

Very pretty land and house. I would try to flank something decorative along the side of that long and wide driveway, whether hardscape or not. Maybe very low wall, with the smooth concrete that mirrors wood, if you know what I am talking about. It is a bit modern like your house but has texture. Then maybe a tile (black) on top. Might be too much for your neighborhood. Not sure about trees or plants for your area as I live in Los Angeles.

In looking at the first photo I was wondering how one gains access to the door. I prefer when there is a clear path to the entrance. I also notice in later pictures that shrubs were planted much too close to the house. My suggestion would be to reshape the border to eliminate the bed on the street side of the path. New shrubs should not be planted so close to the house. The remainder of the beds could be filled with low perennials/ground cover. I do not live in your zone so I can't recommend specific plants. Black or navy blue would be nice for the door.

I think the biggest problem with your house is the lack of architectural balance. I don't know if it is the case or not but the porch does not look original and it looks like the garage side of the house was added on. Right now it looks like two different houses. While I suspect that expanding the porch across the house is out of your budget, If your budget is that size you may wish to double the window and that side of the house. it would help with the balance and get more light into the house. I would balance the house with the landscaping. Something large needs to be planted on to the side of the porch to balance the porch. The idea is to cover the large expanse below this window. This could be a large Rose of Sharon, azalea, lilac, or similar plant the lives in your area. You may want to put the large bush between the window and edge of the house and the spirea, rose of Sharon in this area with the dwarf lilac, azalea between it and the porch. Possible add a garden in that area with either a hard or soft garden wall to cut it form the yard in general. In this garden you could have lilies, daffodils, roses, ie something to add color all year around. I like curves in garden not hard straight lines and walls. Once you have corrected the imbalance then consider what to do with the yard closet to the side walk.
