Would planting a hedge or shrubs on your side be an option? Much nicer than a fence, provides a biotope for birds, insects and other animals, can bear fruit (yummy berries!)

Growing to a hight of 3 ft (~90 cm) should be a matter of 2 or 3 years, depending on the plants.

My dad always had a tin can of glue simmering in a pot of hot water, in his workshop, “back in the days”, 1960s.
