Hi all, I have a 3-meter easement with a manhole in my backyard (please see the attached image), which looks quite unsightly. While I understand I can't build any permanent structures over it, I'd like to improve the aesthetics of the space. There is also a slope in the backyard (around 300 mm) that I’m planning to fill with soil, but I’m unsure how to manage this without covering the manhole. Could I create a treated pine sleeper border around the manhole and fill the surrounding area with soil? I'm also considering adding pebbles around the manhole for a more attractive look. Any suggestions on how to approach this?
