Thanks for the bamboo sheeting idea, Bethjeff. I'll look into that.
Scaredofthedark - I do feel p*ed off that I'm paying £1,000 to access the field - as a one-off and the next door neighbours use it for free all the time. They've still got a swing rope and seat tied onto the only tree in the field, which stands between our properties boundaries. They've really assumed ownership of the field with the gate buitl specially in the fence by the dad.
They've currently got friends staying, with teenager children and the noise has been incredible - starting at 8.30pm - my DCs bedtime and not ending until midnight, as gangs of children jump on their garden trampoline (that used to be in the field) and then run around the field screaming at the v tops of their voices without a single pause for 3.5 hrs at a time, whilst the adults sit talking and laughing loudly right near my bedroom window, getting drunk and louder as the night goes on...
Sorry...bit of a rant, after some sleepless nights.....I just have no idea why any parent would NOT stop their children trespassing, once they've been told firmly NOt to do so, by the owners who've raised the problem of liability if the children got hurt on their own land...
This is my plan....I've now found some fencing on the net (Jacksons Pallisade Palliframe Panels) that will cut off a lot of the view but retain light and air and some of the view through the thin fence slat gaps. Then I'm going to grow climbers up it on my side.
Meanwhile, once my works are finished, I'm going to let the owners know that where the machinery for my works has made ruts in the field grass, at the bottom of my garden and beyond, I'll re=seed this area and re-train the brambles - to return the field to it's previous state, as agreed with them.
However, my ulterior motive is that I'll also get that part of the field temporarily fenced off with orange plastic stuff my builders are using and stick a notice there saying, "Keep off this area. Re-seeding". I'll tell the owners I'm doing this because of the continued trespassing into the field and my concern that whilst I intend to return the field to its previous state, the trespasses may thwart that - hence the retained temporary barrier in part of the field.
I'll then suggest they might want to consider putting up a Trespasses will be prosecuted notice and doing something about the gate in the neighbours fence that accesses the field. I think there are two or three others who've also put gates in their boundary fences to access the field - namely, friends of the neighbours.
Just to add that the situation would have been more tolerable (despite the lack of privacy and constant noise) if the childrne hadn't ganged up on, humiliated and aggressed my DCs. But that made me see red. No one messes with my sons and gets away with it! Not that I want any big confrontation however.
I'd rather take appropriate and legitmate/ legal action to gain my goals.
And when thei neighbour children move on and grow up (hopefully without the teenage phase of drink and rugs and wild parties in the field too!), then I could open up the view again.
