Where is this / which USDA hardiness zone? I can definitely picture a deck wrapping around the house, and you could integrate large planters into the edges of the deck to create a privacy screen through the right plants for your climate. Depending on how much space you have left, I also wonder if you could get a tree or two onto the lot, and then layer native plants of progressively lower heights out towards the sidewalk.

I'm in zone 10b..The exterior has been more of a challenge for me because I want to change the color as well as the facade..I love the idea of the wrap around deck. That was one of my first thoughts, but the interior renovation took more time and budget..I completed the north side landscaping portion of the house, and I'm left with the east side, which includes a pool, south side, and the westside...Here's a pic of my north side when I completed it 8 months ago..My initial idea was to ass more hardscaping (pavers) to break up the large grass area, but I didn't realize the expense of flagstone..Yikes..That will be reserved for a future project

I would add some tiered landscaping. Maybe stone or slump stone brick trimmed planters scattered within the slopes. Some choice bush plants with interesting leaf color.

To break the vastness of the white wall, plant some tall flowering vines or bushes.

LB interiors has a great idea like the "lakefront elevation" to do a elevated garden, possible two tiers. If that is unaffordable perhaps some large narrow trees like the photo below:
