Have you ever noticed how many stately homes are symmetrical in their design? While we’re not suggesting you move into one (although if you can afford it, why not!) you can recreate this look with symmetrical decorations and landscaping at the front of your house.
It could be something as simple as placing identical potted plants on both sides of your front door (topiary trees work really well for this). If you have a wall light, pop one on the other side too.
If your front door is in the middle of your home, you could go a few steps further and have a garden path leading straight from it, then ensure the lawn and beds on either side are symmetrical.
