The fact of space being so tight necessitates the use of plants that comply with the plan. Left of the garage is fairly large shrub. Start turning this into a small tree form so that its bulky part, the canopy, will eventually be over your head where it can serve like a protective umbrella. Near the walk would only be a few upright trunks that do not occupy much ground space. To train it into a tree, make its overall shape similar to a sugar cone, where its tip has been embedded into the earth at the exact place the shrub grows. Trunks and foliage come up through/within the main part of the cone but nothing sticks outside of that shape. After it has reached 8' or more feet tall, you can let branches and foliage spill outside of the shape as if they were a giant blob of ice cream overflowing the the cone. Over time, starting at the bottom of the plant, remove branches, twigs and foliage so that only the bare trunks remain. You can do this to 50% of the plant's total height. (At any time of year, but early spring is the optimum time. Near the end of the growing season is the least optimum time. Plant some low growing annuals, perennials, or groundcover below the tree. (Pick one, not use all three.) See if you could do the same thing at the right side of garage door.' See if you could replace the uppermost garage door panel with one that has a bank of windows in it. Along the narrow path to the front door, I'd ditch the hedge and replace it with low growing annuals, perennials, or groundcover. Since it is long, you wouldn't necessarily need to keep it all one thing for the whole length, though you could if desired. It could be a strip of multicolored impatiens, or a strip of variegated liriope, It it could have color at the beginning and end while the middle run is groundcover. For the blank wall, consider some flat, outdoor art decor. A flag stretched in a frame would work. But there's not room for plants or anything else to stick out into the path.

Why can't you have black shutters? Because your neighbors have them??? Is there a law in your town that you all have to have different color shutters? Anyway you have a very nice home and I happen to think it looks great with shutters. How about a very dark green?

You can also hire a qualified and experienced landscape designer for either an onsite consultation or to develop a planting plan that you can DIY at your convenience. This is a very affordable option, rarely costing more than a couple hundred bucks and should be considered an investment in your property rather than just an expense as it will save you the expense of trial and error plantings and can increase property values. Online design sources tend to be expensive for the value provided and judging by the amount of negative feedback they receive in this forum, are rarely very successful or well received.

I would have a planter just on the right side. Consider moving the rock out from the right side and put it elsewhere. Buy a 24x24 cement square pad and level set it in front of the meter and get a taller planter pot maybe a foot taller in black to set on the cement pad. Get a door mat that compliments with the door color. Future plan might be to extend the left side bed further out, and trim down all the shrubs so they're below the windows. Landscaping will add some nice curb appeal.
