Congratulations on your new home! You have a lovely location, judging by your photos, and you mentioned that you're in the country. Much to love! But did I hear just a note of longing for a little more of that famous southern grace and charm? Something more like this, perhaps?

I know this goes way beyond what you asked, but for what it's worth, here's what I did:

• Removed the rustic wood shutters.
• Painted the downspouts black. (A good gutter contractor might have suggestions for relocating some of the more obtrusive downspouts.)
• Painted the siding in the two small second-floor areas a blue-gray similar to the roof color, so they appear part of the roof.
• Widened the trim at the bottom of the peak vent in the tallest gable, to match the width of the trim running down the slopes. (A small detail, but it helps bring down that too-tall gable.)
• Corrected the builder's handling of the gable returns. The little roof sections at those corners should have a very shallow slope, so they are barely visible (if at all) from the ground and so the under-eave trim pieces that are flat against the wall appear to extend all the way to the horizontal trim (the returns).
• Addressed the mismatched arched sections over the windows. Here I simply replaced those arched windows with wood infill panels, trimmed to follow the curve of the brick above and painted the same blue-gray as the second-floor siding. Another option, if it can be done, is to make those arched windows match the windows below them by removing the extra mullions and thickening the trim (both the upper curve and the verticals that continue the verticals from the windows below). Worst case, that might require completely rebuilt arched sections.
• Moved the doorway light fixtures to the front wall. (If the side-wall lights are needed for stair safety, I would replace them with unobtrusive wall-washers, or use other functional stair lighting.) I would also wash abundant warm golden light over those arched wood entry doors for an inviting glow in that now-dark area (not shown). (If/when the doors need refinishing, maybe consider a lighter stain color?)
• Rebuilt the rather daunting-looking entry stairway to pull the first four steps forward and make a mid-flight landing atop step four, to break the climb into two sections. The pulled-forward section is flanked by brick side walls capped with white limestone (good place for planter containers), and set on a broad, brick-trimmed landing at the bottom. (I can't see the path that ascends from the driveway well enough to know how it should meet this landing. Ideally that ramp--or stairs?--should lead to the landing itself and not to the front of it as shown.)
• Added a wide, brick-trimmed walk from the street to the entry area, flanked by brick/limestone columns with lights (tops at same level, so heights will differ because of the slope). This might not be appropriate in your country location. I did it simply because he house seems to call for this level of formality.

As for plantings, this very assertive house will need equally assertive landscaping: bold sweeps, strong shapes, large masses. I like using white to balance the white trim, but I would use it away from the house, not right next to it where there is already so much white. Would an arc of Little Limes (or Limelights) work on the right side? And could the ginkgo go there somewhere as well, maybe behind the arc near the front/street? (I can't see what's there and don't know how far your property extends.) I've shown the hydrangea arc meeting a low boxwood hedge in front, which in turn meets the brick column at the walkway. (All shrubs are underplanted with a locally-appropriate ground cover.) I left the right-side lawn for play, added a large shade tree and a pink dogwood on the left, both underplanted with azaleas/rhododendrons and ferns for a pleasant ascent from the driveway through a woodland garden. (Obviously any shade tree will take years to grow, so in the meantime, more hydrangeas could make a balancing mass of white bordering lawn to the left of the walk. And of course, dogwoods bloom in spring and hydrangeas later in the summer; they would not bloom simultaneously as shown here.)

A few ideas, anyway--happy dreaming!
