Here's a pic of our home which sits on 1.25 acre sloped lot.
We'd like to do something affordable and creative to the area to the right of the entry in order to try to normalize the elevation a bit. We've just added a courtyard and firepit to the left of the entry and would like to address the sloped area to the right.
The best idea I've heard is to extend the concrete wall to the right of the walkway and fill with dirt. However, the concrete wall was quite expensive. Is there a more affordable option?
It's unknown how much budget you have. On the range of expensive to cheap, the former would be a retaining wall, the top of which is even with your walk to the front door, running down the hill to the end of the house, and faced with matching brick. Plant some hollies or similar evergreens; choose dwarf plants or plan to keep them trimmed so they never obscure more than 2/3 of the brick facing on the house.
On the cheap side, you could buy American or Korean boxwoods, forget the retaining wall, and plant a row next to the house. Trim (shape) them as they grown so the tops of the plants form a parallel line with the brick trim under the windows. Or, depending on your deer situation, you could plant a hedge of photina, and use the same trick.
